When using Technology Level 05, apply IY92037.
#2
If you have updated the host environment by, for example, applying
Oracle-specific patches, the Oracle I/O timeout threshold (MISSCOUNT)
might have been changed. Therefore, when you update an environment,
you need to review the MISSCOUNT value.
#3
Only the NSD (Network Shared Disk) configuration is supported. Set the
usePersistentReserve option to no in the GPFS cluster configuration
information.
#4
VxVM is not supported.
#5
HDLM supports PowerVM Live Partition Mobility in an environment in
which a virtual SCSI device or virtual HBA is used as the HDLM device.
#6
Sometimes, if JFS2 is being used and a crash (halt -q) fails over a node,
the resource to be mounted on the failover-destination node is not
properly mounted. This problem occurs regardless of whether HDLM is
installed.
#7
Apply fix pack 3.3.0.3 or later.
