MU3 Release Notes

Workaround: Reset the parameter to the default value by reissuing tunelinks with

bandwidth=128000 (or higher) and latency=100.

Remote Copy Volumes go Stale Due to Lack of Adm Space (Bug 44963)

The default grow value of 64 GB might be insufficient for volumes which are in Remote Copy

groups. The reason is Remote Copy relies on taking snapshots during the initial sync phase and

also during the resync periods. The snapshots end up using administrator space depending on the

IOPS and throughput load on the Remote Copy volumes.

Workaround: Use setcpg -sdgs <increment_value> <volume_name> to increase the

default grow increment. The recommended value is 96 GB.

controlport Configuration Gives Warning after Being Taken Offline (Bug 44989)

Using the -f option with controlport config, the system responded with a confirmation

request, or refused to force the mode change.

Workaround: If the -f flag was used and the system still prompts for confirmation, respond to the

prompt. If there are other messages, they need to be resolved (e.g. take port offline), or possibly

reissue the command.

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: After the failed upgrade, use the showsched command to determine which scheduled

tasks need to be suspended again. Use the setsched -suspend <schedule_name> command.

Remote Copy: Long Waits for Remote Copy Commands to Return Data

When using a 2-node secondary system for a 2-to-1 Remote Copy configuration, 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 are

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.

IMC Crashes during Rolling Upgrade (Bug 46452)

The IMC receives a fatal error when a rolling upgrade is performed on the HP 3PAR Storage

System.

Workaround: When performing an HP 3PAR Storage System rolling upgrade, it is recommended

that all IMC instances that are connected to that HP 3PAR Storage System be shutdown.

When Windows Server 2008 is rebooted for the first time after an HP 3PAR OS

upgrade to 3.1.1, the Windows Server 2008 will mark the HP 3PAR LUNs offline

A change in the Product Revision level field affects Windows Server 2008 adversely, if the host is

rebooted after an upgrade to HP 3PAR OS version 3.1.1 or any upgrade within the 3.1.1 family

(MUs).
