HP 3PAR InForm OS 2.3.1 Extended MU5 Release Notes (QL226-96621, May 2013)

There is a known issue that can occur with any I/O that is 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 any level of 2.3.1 (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.

as octal numbers, just like many other languages and shells (bash, perl, etc).
