Important Information

Upgrading Issues

G2 E-QIPs

Note: If your G2 E-QIP is configured for DHCP and it has been

disconnected from the DHCP server, you may encounter warning

or error messages stating E-QIPs Failed. This message will occur

after every power cycle, or until the DHCP server is re-connected.

Clear this message and wait for the G2 E-QIP to become available.

This problem occurs because the LC will load faster than a G2 E-

QIP with an unreachable DHCP sever. Once the G2 E-QIP

becomes available, there is no longer a problem.

ITP or None Configuration

Note: ITP and None are no longer options for the G2 E-QIP. They have

been replaced with a free iSCSI option.

If the Ethernet protocol previously enabled for the Gator G2 E-QIP was either ITP or

None, it will be necessary to enable iSCSI on the Ethernet Options screen and re-save

the parameters. After the LCM is rebooted, a error message on the LC will indicate that

one or more of the G2 E-QIPs does not match the previous configuration. Clear this

message and then enable iSCSI using this procedure:

Note: If iSCSI or NDMP was enabled on the previous firmware release,

there should be no configuration problem on the G2 E-QIP. Only

QIPs configured for ITP or None will have a problem.

1. From the Controller Configuration Toolbar, select Partitions then select the desired

partition and then select Edit.

2. In the Edit Partitions screen, select Options to view the Controller Options window

(Figure 1).

3. Select iSCSI and then select Configure.

4. A window will display asking to confirm parameters, select OK. You may now

configure iSCSI as your protocol.

Note: You may only choose NDMP as a protocol if you purchase NDMP

as a keyed option.

Figure 1 Controller Options

window.

Configuring IP Parameters

With static IP setup, enter parameters as normal. For DHCP, enter valid addresses

before selecting DHCP and saving parameters.

Type in valid addresses for IP, Gateway and WINS before checking the Use DHCP and

before clicking on Save.

The DHCP server will furnish the Ethernet parameters that will be used. The

parameters that are entered by the User will be ignored.

Notes on Running in DHCP/WINS/DNS and iSNS Environments

Use of any of these options requires communication to an external server over the

network. If this server is unavailable or cannot be reached at the library power up time

the library or QIP will need to be reset after the server becomes ready.

Using DHCP. DHCP provides all the Ethernet set up information necessary to

communicate on a particular network. An external server on the network provides the

Ethernet set up information to the library. If the DHCP server is not present or cannot

be reached at the time of library power up the library will not be able to communicate

with any host on the network. On power up the library searches for a DHCP server

only for about 3 minutes. If none is found the library or QIP will need to be reset in

Figure 2 The E-QIP Controller Configuration screen.

order to re-initiate the DHCP server scan. The Spectra 2K has this option enabled by

default.

Using WINS. WINS is used to be able to address the library or QIP by the hostname

instead of the IP address. The library only will attempt to communicate and register the

hostname with the WINS server during start-up. If the WINS server is not available or

unreachable at that time the hostname will not get registered but the library or QIP will

still be able to function on the network.

Using iSNS. The name service for iSCSI is iSNS. The iSNS server maintains a list of iSCSI

target names for the devices on the network. The library or QIP will register the names

of the devices, attached to it, with the iSNS server. The list of iSCSI devices on the

network is made available to initiators for the purpose of establishing a connection.

Once the library or QIP iSCSI targets are registered with the iSNS server, the iSNS

option should not be disabled. To disable the iSNS option first, de-register the target

devices from the iSNS server, and then turn off the iSNS option on the library or QIP.

The order of events is important when enabling or disabling iSNS:

1. Configure the Ethernet parameters using the LC.

2. Prepare iSNS server for device registration.

3. Connect the QIP to the iSNS server.

4. Enable iSNS option on QIP.

5. Reboot the QIP.

Note: All library Ethernet parameters need to be configured prior to

registering with the iSNS server. Once the Ethernet parameters

have been configured, it is then okay to enable iSNS and reboot

the QIP.

If you registered your library with iSNS first, you can correct the

problem in either of the following two ways:

• By stopping the iSNS service. To do this, remove the files

MSISNS1.DAT and MSISNS0.DAT from the \\WINNT

directory (on 2000). Then restart the iSNS service.

• Or, reboot the iSNS server.

Best Practices for iSCSI and IP SANs

IP SANs should be based on GigE 1000BaseT network topography. Since backups and

storage networks create a good deal of traffic a dedicated subnet should be utilized. IP

SANs should not be sharing bandwidth with regular user LAN traffic. To increase

performance jumbo frames (9K MTU) should be used.

The best performance with iSCSI is achieved by setting the iSCSI parameters to the

following state:

•R2T=no

• Immediate Data = Yes or no

The parameters below can be set to the maximum values listed below:

• First Burst Length = 128K

• Maximum Burst Length = 256K

• Maximum Max Receive Buffer Length = 64K

Best performance is achieved by setting these values to their maximum value.

Reporting End of Media/End of File for NDMP Backup Applications

Some versions of backup applications use the NDMP version 2 messaging for events

like the reporting of EOM conditions. The NDMP mover agent for the tape library can

be configured to report EOM conditions as EOF or EOM.

Setting EOM Reporting on 12K/20K/64K

The 12K/20K/64K Set QIP NDMP EOM option is configured through a Diagnostic

utility (Figure 3)

Figure 3 Library Diagnostics screen with Set QIP NDMP EOM option selected.
