support.novell.com/docs/Readmes/InfoDocument/patchbuilder/readme_5004180.html).

3.3 Update the iManager Cluster Plug-in

You must remove the existing iManager plug-in for Novell Cluster Services and replace it with the

plug-in that is on the Novell download Web site (http://download.novell.com/). Updating the

iManager plug-in for cluster services resolves sporadic iManager problems specific to Novell

Cluster Services.

To remove the old plug-in, start iManager and then perform the following steps:

1Click the Configure button, then click Module Installation.

2Click Installed Novell Plug-in Modules, then select Cluster Services.

IMPORTANT: If you have installed the iManager plug-in for Archive and Versioning

Services, you must remove it. If you have installed the Storage Management plug-in

(

nssmgmt.npm

) and/or the Shared Storage plug-in (

storagemgmt.npm

), you must remove and

resinstall them.

Select these additional plug-ins to remove them.

3Click Uninstall to remove the selected plug-ins.

4Sometimes the plug-ins may not be correctly removed. To ensure that the plug-ins are removed,

complete the following steps for iManager on either NetWare or Linux as indicated:

4a Go to the

sys:\tomcat\4\webapps\nps\portal\modules

directory on NetWare, or

the

To install the new plug-ins:

1Go to the iManager plug-in download site (http://download.novell.com/

index.jsp?product_id=&search=Search&build_type=SDBuildBean&families=2611&version=

&date_range=&keywords=&x=32&y=7) and download the iManager plug-ins to a directory.

2In iManager, click the Configure button, select Module Installation, select Available Novell

Plug-in Modules, then click New.

3Browse to the directory where you downloaded the plug-ins and add the storage management

(

storagemgmt.npm

) plug-in by selecting it, clicking Open, and then clicking OK.

4Repeat Step 3 to add the NSS plug-in (

nssmgmt.npm

) and the Novell Cluster Services plug-ins

(

ncsmgmt.npm

5Select the Storage Management plug-in (

storagemgmt.npm

), click Install, and then click

Close on the message screen with the text informing you to restart your Web server.

6Click Available Plug-ins and then repeat Step 5 for both the NSS plug-in (

nssmgmt.npm

) and

the Novell Cluster Services plug-in (

ncsmgmt.npm

The plug-ins must be installed in the following order:

storagemgmt.npm

nssmgmt.npm

ncsmgmt.npm

7Restart the Apache Web server.

One way to do this is by restarting your server.

3.4 Software Dependency Conflicts on Linux

During the installation and uninstallation processes, a message might appear stating that requisite

software is not installed and asking you if you want to resolve conflicts. Click Yes, and then on the

Dependency Conflict screen, select Do Not Delete novell-cluster-services-cli, click OK -- Try Again,

and then Accept.

You might also encounter software dependency conflicts unrelated to Novell Business Continuity

Clustering or Novell Cluster ServicesTM software. You should resolve these conflicts on a case-by-

case basis.

3.5 Drive Mappings to NetWare Mapped Volumes Missing After

Install

The drive mappings to all NetWare mapped volumes are removed if you enter invalid credentials for

administrator/password in the BCC install wizard.

3.6 Limited Support for Mixed NetWare and Linux Clusters

Clusters containing NetWare and Linux* nodes are only supported in a BCC as a temporary means

to convert a cluster from NetWare to Linux. Part of the temporary conversion state includes a

restriction that only one mixed cluster can exist in your BCC. For example, Cluster A can have both

NetWare and Linux nodes, but Cluster B cannot. All nodes in Cluster B must be either NetWare or

Linux.

Novell Business Continuity Clustering 1.1 SP1 Readme 5

The same restrictions that apply to migrating or failing over resources between nodes within a single

cluster also apply to migrating or failing over resources between clusters in a mixed BCC. You can

only migrate or fail over NSS pool/volume resources between clusters in a mixed BCC. See

Converting a NetWare Cluster to Linux (http://www.novell.com/documentation/oes/

cluster_admin_lx/data/bu1b1x8.html) in the OES Novell Cluster Services 1.8.2 Administration

Guide for Linux

3.7 Do Not Mix IDM Versions

Do not install IDM 3.x management utilities with the IDM 2.x engine. If you do, the IDM Driver for

eDirectory will be converted to version 3.x, and the IDM 2.x engine will no longer be able to get the

driver information.

4.1 Existing Clusters Could Have Conflicting VOLIDs

When existing clusters are configured and enabled within the same business continuity cluster, the

volume IDs (VOLIDs) for the existing shared volumes might also share the same VOLIDs. To

correct this problem, manually edit the load script for each volume that has been enabled for

business continuity and change the VOLIDs to unique values for each volume in the business

continuity cluster.

4.2 Refresh of iManager Views Delayed

When you enable a cluster resource for business continuity, that resource might take up to 30

seconds to appear as enabled for business continuity in iManager. After Business Continuity

Clustering refreshes its status information, the resource will appear as enabled.

6Novell Business Continuity Clustering 1.1 SP1 Readme

4.3 NSS Pool Failover Times

Due to MSAP (Multiple Server Activation Protocol), the NSS pools on a cluster might take up to 30

seconds per pool to fail over from a cluster to one node in another cluster. If you have several pools

in a cluster, the failover process will be faster if those pools fail over to multiple nodes (fan-out

failover) rather than to just a single node.

4.4 Migrating Volume Trustee Assignments

If you are migrating a pool to a cluster in another tree and you want to maintain that pool's volume

trustee assignments, you must migrate the pool to a server with an eDirectoryTM replica that holds all

objects that have trustee assignments on any of the volumes in the pool. After migrating the pool to

a server with an eDirectory replica, enter the following console command on that server for each

volume in the pool:

NSS/ResetObjectIDStore=volumename

This command updates all volume trustee assignments and should be run at night, on a weekend, or

during a period of low network and disk utilization. Trustee assignments will not appear in

management utilities until you run the command.

If you migrate the pool to a server in another tree without an eDirectory replica, within 90 days you

must migrate that pool to a server with an eDirectory replica and then run the command for each

volume.

Trustee assignments are always enforced, but after migrating a volume from a cluster in one tree to a

cluster in another tree, volume trustee assignments might not be displayed correctly in

ConsoleOne®, Novell Remote Manager (NRM), or on an NCPTM client. This issue exists when the

migrated pool is active on a nonreplica server node.

The trustees are in place and correct. Users with trustee assignments from the original tree can map

drives and access data with no issues. If a pool is migrated to a server node that contains a replica,

the trustee assignments are presented correctly.

See Migrating Volume Trustee Assignments above for more information.

4.5 Renamed BCC Volume Names Don't Replicate to Other

Trees

If you rename a volume on a shared pool in a business continuity cluster, the changed volume name

will not replicate to a cluster in another eDirectory tree. This does not affect user access to the

volume in either tree.

4.6 Using iManager to Set Credentials on Linux Not Functional

You cannot use iManager on Linux to set eDirectory credentials for BCC. You must use iManager

on NetWare or Windows (the server must be in the same eDirectory tree), or use the Linux BCC

command line interface from a shell prompt to set credentials.

Novell Business Continuity Clustering 1.1 SP1 Readme 7

4.7 Problems Saving SAN Management Scripts

After filling in the values on the SAN Management Script Details page and clicking Apply and OK,

you are returned to the Resource Properties page (with the Business Continuity tab selected). You

must click OK on the Resource Properties page or your script changes will not be saved.

4.8 Resource Goes Offline After Migration

Occasionally after migrating a resource to another cluster, the resource will be in an offline-primary

state on the destination cluster. If this occurs, online the resource on the destination cluster using

either iManager or cluster commands at the server console.

4.9 Cluster and Peer Clusters Don’t Appear in Connections List

After Upgrade

After upgrading from BCC 1.0 to BCC 1.1 the cluster and peer clusters in your BCC might not

appear in the connections list in iManager. To work around this problem:

1Deselect the Enable Business Continuity Features check box in iManager and save your

changes.

2Re-enable Business Contintuity by selecting the peer clusters and selecting the Enable Business

Continuity Features check box.

For more information, see Configuring Clusters for Business Continuity in the Novell Business

Continuity Clustering 1.1 Administration Guide for NetWare.

4.10 Creating a New Cluster Resource Requires IDM Cluster

Node to Be Up

The node in each cluster where the IDM engine and drivers are running must be up before creating a

new cluster resource in your BCC. This requirement does not apply for configuring existing cluster

resources, just for creating new resources.

4.11 Disabling BCC for a Cluster Disables BCC for Cluster

Resources

If you disable BCC for a cluster using either iManager or the Cluster Disable console command,

BCC will also be disabled for those cluster resources that have been BCC-enabled. If you re-enable

BCC for the cluster, you must re-enable each individual cluster resource that you want to be BCC-

enabled.

This can be a time-consuming process if you have many BCC-enabled cluster resources. For this

reason, you should use caution when disabling BCC for an entire cluster.

4.12 Cluster Restart Command Not Functional on NetWare

The

Cluster Restart

command currently does not work on NetWare clusters. To restart your

cluster:

1At the NetWare server console of a cluster server, enter

unload ncscon

8Novell Business Continuity Clustering 1.1 SP1 Readme

2Enter

cluster restart

3Enter

load

ncscon

This problem will be fixed for NetWare 6.5 Support Pack 7 and later. Unloading ncscon will then no

longer be required.
