Upgrading Disk Drive Firmware In An Hp Continuous Access Eva Environment; Saving Storage System Configuration Information - HP 6100 Software Manual

CAUTION:
In an HP Continuous Access EVA environment, do not begin the upgrade until the following conditions
are met. If you attempt to upgrade the controllers before the following conditions are met, controller
operation will fail.
Ensure that no DR group is logging, merging, or copying. Furthermore, none of the DR groups
can be in a failsafe locked state.
1. Click the DR group icon in the Navigation pane.
2. Check the Log state in the DR Group Properties window.
Ensure the connection between the storage systems 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 storage systems must be running normally with fully functional controller pairs.
After upgrading the first storage system (for example, the source), wait at least three minutes and
no more than 60 days before upgrading the second storage system. Ensure the preceding conditions
are met on the second system.

Upgrading disk drive firmware in an HP Continuous Access EVA environment

When upgrading disk drive firmware in an HP Continuous Access EVA environment, the following
requirements must be met:
• Verify that all DR groups are not failsafe mode enabled or in the failsafe locked state (DR group
failsafe mode should be disabled).
• Suspend replication and disable the intersite link or modify zoning to isolate the source array from
the destination array.
• Upgrade the disk drive firmware on the destination array.
• Re-establish intersite link communication between the arrays and resume replication, allowing the
DR group merges to complete.
• Perform site failover.
• Suspend replication and disable the intersite link or modify zoning to isolate the source array from
the destination array.
• Upgrade the disk drive firmware on the new destination array (before site failover, this was the
source array).
• Re-establish intersite link communication between the arrays and resume replication, allowing the
DR group merges to complete.
• Perform site failback.

Saving storage system configuration information

Estimated time to complete: 10–15 minutes
When to perform: As close as possible to the upgrade
Before starting the upgrade, collect and save your current configuration information. This information
can be used to restore the existing configuration if necessary. The configuration data is saved to a
series of files stored in a location other than on the storage system. HP Storage System Scripting Utility
(called the utility) is used to collect configuration information.
