HP P6000 Replication Solutions Manager 5.3 Release Notes (T3680-96402, May 2011)

Job scheduler does not handle Daylight Savings Time properly
The job scheduler handles Daylight Savings Time (DST) correctly in the replication manager unless
you try to schedule a job on the day that DST changes (spring or autumn). For example, if DST begins
on Sunday at 2:00 a.m., and you try to schedule a job that day, one hour is added to the time. (The
job scheduler increments the scheduled jobs by one hour.)
Resolution: If you want to schedule a job on the day that DST changes, you must set the job one hour
earlier than required. However, if you try this procedure on any day after the day that DST begins,
the job scheduler will work as expected.
Clarification of WaitDrGroupSynchronizationTransition job command
The description of the WaitDrGroupSynchronizationTransition job command states that the
job is halted until the I/O mode of the DR group is changed. However, the job behavior is as follows:
• If the DR group is in enhanced asynchronous mode and you change the mode to
synchronous, the job waits until the state of the log is merging (log running down), not
until the I/O mode has changed to synchronous.
• If the DR group is in asynchronous mode and operating normally, the job does not wait.
FractureHostVolumeMirrorclones job command limitation
You can use the FractureHostVolumeMirrorclones job command for multiple mirrorclones on
the same host. However, you can only mount one host volume from each mirrorclone. You must mount
all other mirrorclones manually. This job command does not work for multiple mirrorclones on different
hosts.
Scheduled job events do not run
In the events pane, one of the following messages is displayed:
Internal error occurred starting job <job name>.
Missed scheduled execution time of <job name>.
Resolution: The security credentials (user name and password) that were saved with scheduled job
events might be incorrect. This can occur if the security credentials have been changed on the HP
P6000 Replication Solutions Manager server. For information on changing the job security credentials,
see the HP P6000 Replication Solutions Manager Job Command Reference.
Other replication manager issues
Installing Open-FCoE on SUSE Linux Enterprise Server 11
If you have a host running SUSE Linux Enterprise Server 11 for x86, and you install Open-FCoE on
that host, HP P6000 Replication Solutions Manager indicates that the host is in an unknown state. To
prevent this situation:
1. Open the host's etc/hba.conf file in a text editor and comment out the line org.openfc
/usr/lib/open-fcoe/libhbalinux.so.1.
2. Save the file.
3. Restart the host agent.
Enabling Add Presentation for a virtual disk that is being extended
Do not enable Add Presentation for a virtual disk that is being extended. A virtual disk must be in a
normal operational state before presenting it to a host. See the “Remote replication guidelines” chapter
in the HP P6000 Replication Solutions Manager User Guide for more recommendations about virtual
disks.
