Release Notes

The following late-breaking information supplements theHP SureStore NetStorage User's Guide and online

help. If information in the User's Guide conflicts with information presented here, the information in this file

should be considered correct.

OS Upgrade

OS Version: After upgrading from the original version of the OS (build 81) to version 3.3.x.x you cannot go

back to the original version without risking data corruption. If your file volumes are very large, the upgrade

process may take considerable time to complete. The progress of the upgrade can be seen on the HP

NetStorage 6000 LCD display located on the front panel of the unit.

Administrative Password Challenge for Internet Explorer 5.5: When upgrading from software build 81

to version 3.3.x.x, you may be challenged for an administrative password whether or not you set one

previously. In order to correct this problem, you need to:

·Clear your local cache

·Circumvent the web proxy cache

To clear your local cache and circumvent the web proxy cache:

1. Open Internet Explorer.

2. Select Tools > Internet Options.

3. Under the General Tab, in the Temporary Internet Files section, click Delete Files.

4. In the confirmation dialog box, click OK.You may optionally choose to delete your off-line content

stored locally at this time.

5. Under the Content Tab, in the Certificates section, select Publishers.

6. Select every occurrence of Hewlett-Packard or Hewlett-Packard Company, if any exist, and click

Remove.

7. Click OK.

If you use a proxy server:

8. Under the Connections Tab, select LAN Settings.

9. In the Proxy Server section, check the box toBypass proxy server for local addressesand click

OK.

10. Click OK again to close the Internet Options dialog box.

11. In order for you settings to take effect, you must shut down Internet Explorer and restart it.

Administrative Passwords: When upgrading from software build 81 to version 3.3.x.x, the administrative

password is lost. The administrator must input the password again after the upgrade.

Share Level Security Passwords:In software build 81, share level security passwords werenotcase-

sensitive. In software version 3.3.x.x, share level security passwords are case-sensitive. For example,

JaneD561 and janed561 would not be recognized as the same password.

General

Administrative GUI Access: Access the administrative GUI pages directly through the HP NetStorage

6000 address (either IP or name) rather than attempting to access through an IIS server that is redirecting to

the HP NetStorage 6000. Occasionally this hangs the device and it is necessary to reboot to access it

again.

Renaming extended File Volumes: The HP NetStorage 6000 does not allow extended File Volumes

(volumes that have been extended across two partitions) to be renamed.

Context-sensitive help: The HP TopTools help button is not context-sensitive to the HP NetStorage 6000

page you are viewing. Press the?button in the upper right corner ofthe page to view context-sensitive help.

IP address: If DHCP is enabled, but fails, the HP NetStorage 6000 may revert back to a previously

assigned static IP address. This may lead to some confusion as the NetStorage web interface indicates that

DHCP is enabled (which it actually still is), even though it failed and the IP address was not DHCP

generated.

Front panel Ready message: The front panel LCD displays Readyprior to the HP NetStorage 6000

actually being accessible. You should wait until the LCD displays the System Name and CPU Load before

trying to access files.

Backup -single file restore: When doing a single file restore the name of the file being restored is NOT

case sensitive. As an NFS client, when you restore a file that contains the same characters, you will get a

restore of all the files. For example, a file named GoodDoc, GOODDOC, or gooddoc will all be restored as a

single file restore operation.

Spanned tapes in backup: When a single file spans two tapes during a backup operation it is possible that

the ACL information for this file may be corrupted. The data integrity of the file is however, never in

jeopardy. To restore the ACL an administrator or root can take ownership of the file and set the appropriate

permissions.

NIC port order: The PCI bus is scanned from right to left (as viewed from the front of the HP NetStorage

6000). NIC cards would, therefore, be expected to be discovered in the same order. However, single port

NICs are always discovered before dual port NIC cards and may, therefore, cause confusion regarding the

mapping of physical ports to port numbers. In general, scanning from right to left (as viewed from the front of

the HP NetStorage 6000), the first single port NIC is Port 1. For dual port NICs, the bottom port is numbered

logically lower than the upper port.

Dual-port NIC card: Computer Associates Unicenter TNG Framework may have problems properly

detecting and classifying an HP NetStorage 6000 box that is using a dual-port NIC card. If this problem

occurs, one port is properly identified under Network_Storage> HP_Storageand an icon is displayed in the

Unicenter TNG 2-D Map. The other port is classified under Interface > IP_Interfaceand does not have an

icon associated with it. All traps associated with the HP NetStorage 6000 are sent to the Unicenter TNG

Event Console Log. If using a dual-port NIC card, it is recommended that the Unicenter TNG Event Console

Log is used to manage the HP NetStorage device rather than the Unicenter TNG 2-D map.

Multi-NIC connectivity: Connectivity issues may arise on a multi-NIC HP NetStorage 6000 if a client is

running Windows 95/98 or NT Service Pack 5 and trying to access the NetStorage 6000 by its IP address.

Possible workaroundsinclude upgrading the client to NT Service Pack 6 or accessing the NetStorage 6000

by its system name instead of its IP address.

Host file management: The NetStorage web interface does not allow a host to be added to the local host

file if the host is already present in the host.nisfile. A work around is to bypass the web interface and

manually add the host entry to the local host file.

File Security: NT Security Descriptorsdisplay the wrong owner information if the domain\administrator

takes ownership of the file. Instead of displaying the owner as domain\administrator,

XXXXX\administratordisplays (where XXXXX is the HP NetStorage system name).

File Security:Domain\administratorthat have no rights to a file can still change the permissionson a file

without first takingownership of it.

File Security: If the system is a member ofa Windows 2000 domain(configured in mixed mode), with trust

relationships to other domains, then taking ownership of files may not work as expected. Domain users on

NT 4.0 workstations will not be able to take ownership of files stored on the NetStorage 6000. On NT 4.0

workstations, only domain administrators will be able to take ownership of such files. On Windows 2000

workstations, this limitation does not exist, although the user may see an erroneous message box stating the

contrary.

User mapping strategy: An NT to UNIX user mapping strategy (no user mapping, user name mapping or

full name mapping) should be chosen prior to giving end users access to the HP NetStorage 6000. Based

on the mapping strategy selected, the system adds entries to theuser map files (even if no user mapping is

selected). Changes to mapping after users have already attached or created files may result in users not

having expected ownership of previously generated files or expected mapping not taking place on newly

generated files.

Workstations with login restrictions: In cases where an administrator has established workstation login

restrictions (for example where a user is restricted to logging into one workstation and one workstation only)

they will be challenged for a password and will be unable to access the NetStorage 6000. The administrator

should remove login restrictions to prevent this problem.

Removing a user or group: Entries in the user map file are not automatically removed when a user is no

longer in the passwd.nisfile. Entries in the map file must be manually deleted.

Entries in the group map file are not automatically removed when a group is no longer in the group.nisfile.

Entries in thegroup map file must be manually deleted.

After Backup, file volumes disappear: After restoring files from a backup tape the browser may contain

stale or incorrect information about the file volumes. Selecting Storage > File Volumes shows that no file

volumes are configured. Either click theRefresh button on the browser for the correct file volume

information to appear, or close the browser window and open another one.

E-mail Notifications: The URL pointing to the failed device always uses the host name instead of the IP

address, even if the host name is not resolvable via DNS. In such cases, clicking on the URL causes

unpredictable behavior.

System log online help: The online help for the system log references specific notes for Redhat Linux 6.1.

This note should include Redhat Linux 6.x and 7.0.

Shared resources: There is a known issue with reusing a share point name after deleting a shared

directory from a client OS (as opposed to removing it from the NetStorage 6000 web management user

interface). The share name cannot be used again since the NetStorage 6000 retains this name and will

indicate that the name is still being used. The only way to remove the name is through the telnet interface.

For example, if a share point is created in the web management interface for directory \vol1\SharedDocs,

called SharedDocs, and this directory is then deleted from a Windows NT client (not using the web

management interface), the share nameSharedDocs cannot be used again as a share point name.

Partition Size Limit: The HP NetStorage 6000 has a limit of 256GB (262144 MB) per partition.

File Volume Size Limit: You must select 262144MB or less when formatting partitions into file volumes. To

create a file volume that is greater than this, simply use the “Expand File Volume” feature to distribute space

across multiple partitions.

DLT Autoloader 818: This device has a maximum native capacity of 320GB, and a compressed capacity

between 480GB and 640GB, depending on compression efficiency. On an HP NetStorage 6000 that is fully

loaded with 73GB drives, it is possible that the stored data will exceed the storage capacity of the tape

device. In such situations, split the data into at least two sets, and back up each data set separately.

Drive Rebuild Time: When rebuilding drives, it may take a long time to initialize a logical drive (RAID set)

containing 73GB drives. The rebuild time is dramatically affected by how much the logical drive is being

used for file serving operations at the time of initialization. This also applies to logical drives that have failed

over to a hot spare, and to the rebuild of a replaced drive.

Reboots after Drive Changes: When drives are removed, added, or replaced while the system is powered

down, it is normal for the device to execute two boot sequences when it is powered on. This is required to

synchronize the RAID controller with the new drive configuration.

IBM Tivoli NetView –This management application is no longer supported.

General Browser Issues

Performance: After changing NIC parameters and clickingApply, the browser may appear to hang while

the operation completes. The delay in the system responding is a function of the number of NIC ports and

changes requested.

Performance: Browsing the directory tree, and deleting directories from within the configuration interface

can take a long time, depending on the number of files and directories stored on the system. During such

operations, the web browser may appear to hang.

Security warnings: Denying additional privileges to Hewlett-Packard in a security warning window in

Netscape generates additional security warning windows. Granting privileges in one of the succeeding

windows does not actually grant the privileges needed. You must grant privileges on the first security

warning window.

Internet Explorer Issues

Error on exit: Some versions of Internet Explorer may generatethe following application error on exit:

The instruction at "(some address)" referenced memory at "(some other address)." The memo

ry could not be "(read or

written)."

This does not cause any problems managing the HP NetStorage 6000, but is a nuisance. Try upgrading to

the latest version of Internet Explorer to solve this.

Viewing multiple devices: You may not be able to view pages from two or more HP NetStorage 6000s at

the same time with some versions of Internet Explorer. Additionally, you may not be able to view pages from

two or more web-manageable devices that have similar user interfaces. Upgrading to the latest version of

Internet Explorer version may solve this.

Netscape Navigator Issues

Netscape Navigator ver. 6.0: The NetStorage 6000 web management user interface does not support

Netscape Navigator ver 6.0. Use a previous version of Netscape or Internet Explorer to view the

management GUI.

Java applets: The NetStorage 6000 interface is a web-based utility that makes extensive use of Java

applets. In some versions of Netscape, Java applets are known to fail to execute on occasion. If some

portion of the management interface fails to function, re-launch the browser to reload the applets.

Index search: If you are on a UNIX system and using Netscape as your browser, the search field in the

index of the online help may not display correctly. You can use the scroll bar to locate the entry you are

looking for.

Resizing browser window: On UNIX systems using Netscape, resizing the browser window may cause the

entire management interface to reload. When this happens, the browser may not advance past theLoading

HP NetStorage 6000... page. If this happens, press the browser's Reload button.

Event log scrolling: On UNIX systems using Netscape, theStatus > Event Log page may not show a

scroll bar. Click in the event log area and use an arrow key; the scroll bar should then appear.

Browser loading: On UNIX systems using Netscape, the browser window may not advance past the

Loading HP NetStorage 6000... page when you press Reload. If this happens, press Reload again.
