E.32 June 2010 Scheduled Maintenance

Updates were made to the following sections. The changes are explained below.

E.32.1 Configuring and Managing Cluster Resources

Location	Change
Naming Conventions for Cluster Resources	This section is new.

E.32.2 Configuring Cluster Policies and Priorities

Location	Change
Configuring Cluster Event Email Notification	The subject line provides information about the cluster name, resource name, action taken, and node name.

E.32.3 Console Commands for Novell Cluster Services

Location	Change
SCAN FOR NEW DEVICES	You can use the rescan-scsi-bus.sh script to scan for the new devices on Linux without rebooting. For information, see Scanning for New Devices without Rebooting in the SLES 10 SP4: Storage Administration Guide.

E.32.4 Installing and Configuring Novell Cluster Services on OES 2 Linux

Location	Change
SBD Partitions	When you mark a device as Shareable for Clustering, the share information is added to the disk and consumes about 4 MB. This space is used in addition to the space needed for the SBD. For example, if you create a 1 GB (1024 MB) device for the SBD, 4 MB are used for the share information, leaving 1020 MB as available free space for the SBD partition.

E.32.5 Managing Clusters

Location	Change
Generating a Cluster Configuration Report	The Monitoring script is included in the report for each resource.
Generating a Cluster Configuration Report	Step 6 provides instructions for how to save the report to a file.
Preventing a Cluster Node Reboot after a Node Shutdown	Novell Cluster Services has been modified to handle panic situations for a node according to the Linux kernel panic setting on the node.
Creating a Non-Mirrored Cluster SBD Partition	In Step 1, added the -s option to the command and example. Step 5 is required only if Cluster Services was initially installed without an SBD partition or mirrored SBD partitions. However, it does no harm to verify that the NCS: Shared Disk Flag attribute is enabled.
Using SBDUTIL to Create a Mirrored Cluster SBD Partition	In Step 4, added the -s option to the command and example. Step 5 is required only if Cluster Services was initially installed without an SBD partition or mirrored SBD partitions. However, it does no harm to verify that the NCS: Shared Disk Flag attribute is enabled.
