HP StorageWorks Clustered File System (software-only) 3.6.1 Windows Storage Server Edition upgrade guide (T4422 - 96001, August 2008)

Chapter 5: Post-Upgrade Steps 33
Replace Membership Partitions That Are Too Small
In HP Clustered File System 3.6, the minimum size for a membership
partition has been increased to 1 GB. This change was needed in part to
provide room for the new mxds datastore. If an existing membership
partition is too small to accommodate the mxds datastore, alert 13914 will
be generated:
The minimum size for a membership partition is 1GB. The specified
partition is too small and should be replaced. If three membership
partitions are configured, you can replace the partitions while the
matrix is online. (Use the Replace feature on the Storage Settings
tab of the Configure Matrix window.) If only one membership
partition is configured, add two more partitions using the Add
feature on the Storage Settings tab and replace the original
partition.
To replace a membership partition, open the Configure Cluster window
and go to the Storage Settings tab, which shows the size of each
membership partition. If a partition contains less than 1 GB, select the
partition, click Replace, and then select a new partition. If three
membership partitions are configured, the replacements can be done
one-at-a-time while the cluster is online. See “Manage Membership
Partitions” in the HP StorageWorks Clustered File System Administration
Guide for more information.
Recreate Concatenated Dynamic Volumes
After the upgrade to HP Clustered File System 3.6.1, you will see log
messages reporting the following for each concatenated dynamic volume:
DynvolWarn: psvXX has old device format and should be
manually upgraded.
Until these dynamic volumes are recreated, you will not be able to use the
new volume disaster recovery feature. You can continue to use
concatenation when you recreate the volume.
CAUTION: Be sure to back up the filesystem on the volume before
recreating the volume. This procedure requires that you also
recreate the filesystem on the volume, which destroys all data
