Install
The drive mappings to all NetWare mapped volumes are removed if you ent er invalid credenti als 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 exi st in your BCC . For exam ple, Cluste r A can hav e both
NetWare and Linux nodes, but Cluster B cannot. All nodes in Cluster B must be either NetWare or
Linux.
4 Novell Business Continuity Clustering 1.1 SP1 Readme
Page 5
The same restrictions that apply to migrating or failing over resources betwee n nodes within a single
cluster also apply to migrating or failing over resources betw een clus te rs in a mixed BC C. You can
only migrate or fail over NSS pool/volume resources between clust ers 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 Driv er 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.
Novell Business Continuity Clustering 1.1 SP1 Readme 5
Page 6
4.3 NSS Pool Failover Times
Due to MSAP (Multiple Server Activation Protocol ), the NSS poo ls 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 th at pool's volume
trustee assignments, you must migrate the pool t o a server with an eDirectory
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 wit ho ut an eD irectory 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 cluste r in one tree to a
cluster in another tree, volume trustee assignments might not be displayed correctly in
ConsoleOne
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.

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.

4.7 Problems Saving SAN Management Scripts
After filling in the values on the SA N Man agemen t Sc ri pt D etails page and cli cking 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:
1 Deselect the Enable Business Continuity Features check box in iManager and save your
changes.
2 Re-enable Business Contintuity by selectin g the peer clusters and selecting t he 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 driv ers are running must be up before creating a
new cluster resource in your BCC. This requirement does not apply fo r 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 BCCenabled.
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.
