HP 3PAR InForm OS 3.1.1 MU1 Release Notes

Issues Causing a Change to the InForm Configuration
The following issue causes a change to the InForm configuration when downgrading from InForm
OS release 3.1.1.
• Host Personas - If a system running InForm OS release 3.1.1 is downgraded, host persona
fields are cleared and the old port persona settings resume effect. However, these settings are
not kept up-to-date nor are they converted back on downgrade, so they will not reflect any
configuration changes made since loading 3.1.1. On a system which only ran 3.1.1, there
will be no port persona settings to revert to.
Prior to the downgrade, a check is run to ensure the system can run in the downgraded state.
If host persona specific configurations are detected, a message is issued. This condition will
need to be resolved before the downgrade is permitted. One example of this would be different
host persona settings sharing a port which can not be supported via port personas.
Running Recovery Manager and Remote Copy (from outside of Recovery Manager)
at the Same Time is not Supported
To synchronize Recovery Manager snapshot data from the production site to secondary site,
Recovery Manager makes direct programmatic calls to the 3PAR Remote Copy product to perform
the background synchronization. When Recovery Manager is doing Application Consistent Remote
Syncs using Remote Copy in Asynchronous Periodic Mode, it is not required to setup the periodic
resync time for the Remote Copy groups. Setting up periodic resync time for Remote Copy groups
when recovery manager is active could disrupt the operation of Recovery Manager.
• Workaround:
Remote Copy can support the mixture of Recovery Manager snapshots and Remote Copy snapshots
(outside of Recovery Manager) if the following procedure is followed:
Inside the Recovery Manager Windows scheduler script:
1. Set the Remote Copy period to 0.
2. Verify Remote Copy SyncStatus as "Synced".
3. Execute Recovery Manager snapshot creation for Remote Copy.
4. Wait for SyncStatus to be completed and Recovery Manager to take snapshot of secondary
volumes.
5. Recovery Manger will monitor the SyncStatus to be "Synced" every 120 seconds as default
then issue snapshot creation of secondary volumes.
6. Reset Remote Copy period to the sync period it was at prior to setting to 0 in step 1.
WARNING! Steps 2 and 4 are critical to ensure Recover Manager-created snapshots and
Remote Copy-created snapshots do not interfere with each other.
