Preparing The Hp P6000 Continuous Access Environment For An Upgrade - HP 4400 Software Manual

3. Verify that there are no changes to the array configuration in progress (such as creation,
deletion, shrinkage, expansion, and presentation). Do not make any configuration changes
within 48 hours of beginning the upgrade. Use proactive event notification to alert you if a
critical event occurs during the 48 hours before the upgrade.
NOTE:
The leveling process does not impact the upgrade. Leveling is suspended during the
upgrade and resumed when the upgrade is complete.
Suspend any processes or applications that may change the array configuration, such
as backups and snapshot creation or deletion. Stop any HP Storage System Scripting
Utility scripts that are scheduled to run automatically.

Preparing the HP P6000 Continuous Access environment for an upgrade

NOTE: HP P6000 Continuous Access is currently available with server-based management only.
Estimated time to complete: Varies depending on replication configuration
When to perform: As close as possible to the upgrade
When upgrading an array in an HP P6000 Continuous Access environment, the following
requirements must be met:
Perform the controller software upgrade using the local management server (the server running
HP P6000 Command View that is local to the array being upgraded).
Before you upgrade the controller software, you must upgrade HP P6000 Command View
(and layered applications) to the required version on both the source and destination arrays.
Before you upgrade an array in an HP P6000 Continuous Access environment, ensure that
all arrays in the storage network are running the same version of controller software. This
ensures that when you upgrade one array, the storage network will have only two versions
of controller software. You cannot have more than two versions in an HP P6000 Continuous
Access environment.
For all DR groups, ensure that the failsafe state is Unlocked and the Failsafe on unavailable
member mode is Disabled.
If the HP P6000 Continuous Access arrays are running different controller software versions,
you cannot make any configuration changes to the arrays (for example, do not add or delete
DR groups or members of DR groups).
You must perform the upgrades to the arrays in the HP P6000 Continuous Access environment
within 60 days (1,440 hours) so that all arrays are running the same controller software
version. After upgrading the first array, wait at least three minutes before upgrading the second
array. Ensure that the previously described requirements are met on the second system.
If you need to upgrade both VCS and XCS, complete the upgrade of one before upgrading
the other. For example, upgrade all arrays running VCS before upgrading arrays running
XCS.
Ensure the connection between the arrays is not compromised or failed.
1. Click the Data Replication folder in the navigation pane.
2. Check the connection state in the Data Replication Folder Properties window.
All EVA arrays must be running normally with fully functional controller pairs.
