3PAR InForm OS 2.3.1 MU4 Release Notes (QL226-96261, September 2011)

showtask for updatevv Displays Incorrect Completion Time (Bug 46328)
showtask for updatevv displays the incorrect completion time.
Workaround
In these cases updatevv did complete for all virtual volumes in the set, however the completion time
is incorrect. The actual completion time can found by gathering the creation time of the new snapshots.
Tasks Become Active after a Failed Upgrade (Bug 46418)
There are certain situations after a failed upgrade when tasks that were scheduled and suspended
become active.
Workaround
Following the failed upgrade using the showsched command to determine which scheduled tasks
need to be suspended again. Use the setsched -suspend <schedule_name> command.
Remote Copy: Possibility of Secondary Volumes going out of Syncwith Primary Volumes with
fail_wrt_on_err Policy (Bug 46443)
The intent of a synchronous Remote Copy group with the fail_wrt_on_err policy is to fail any
host I/O that cannot be successfully mirrored to the secondary cluster. There are a number of
circumstances where the host write can get a failure when fail_wrt_on_err policy is enabled: 1) a
remote copy target failure, 2) failure of the secondary cluster or, 3) a shutdown of the primary cluster.
There is a known issue that can occur with any I/O that has been aborted as a result of an unsuccessful
write to the secondary cluster with fail_wrt_on_err policy; that is, data may get written
successfully to the primary cluster and not to the secondary cluster and host I/O fails with errors. This
will lead to a primary volume going out of sync with respect to secondary volume.
Workaround
1. When the host I/O is completed with errors, start a full sync of the remote copy group having
that VLUN.
2. Use the no_fail_wrt_on_err policy, which is the default policy.
CIM Server Core after Upgrade from 2.2.3.116 (MU1) to 2.2.4.160(MU6) (Bug 50476)
After the CIM Server starts, it sends SLP service requests in multicast to advertise availability of the
SMI-S service capability, including the host and port. If the host address or port field is missing from
the multicast message, the problem can occur.
Workaround
None.
Remote Copy: Long Waits for Remote Copy Commands to Return Data
Commands can take quite some time to return on a busy system. For this reason, the secondary Remote
Copy system cannot be used as a standalone system. Commands such as showrcopy and showvv
have been observed to take between 2 and 8 minutes to return data. Remote Copy operations are
not impacted, however during the time of a DR restore, where multiple resyncs to different targets
could be taking place, commands can take a significant amount of time to execute.
