Hardware and controller software
Data Replication Protocol changes after controller software upgrade
In an HP Continuous Access EVA configuration, the Data Replication Protocol may change to HP
SCSI FC Compliant Data Replication Protocol when the array being upgraded to XCS 09534000:
• Is an EVA4400 that was initialized at a controller software version earlier than XCS 09500000.
• Is an EVA6400 or EVA8400 that was upgraded from an EVA4400 (data in place upgrade)
and was initialized at a controller software version earlier than XCS 09500000.
Symptoms of this issue are:
• Data replication stops after the upgrade.
• There are no visible paths to the destination array. To determine if there are visible paths,
select the Data Replication folder in the HP Command View EVA navigation pane. When the
Data Replication Properties Folder window opens in the content pane, select View remote
connections.
To resolve this issue, you must set the protocol to HP FC Data Replication Protocol in HP Command
View EVA as follows:
1. Select the upgraded array in the EVA Storage Network Properties window.
2. Select the Data Replication folder in the navigation pane.
The Data Replication Properties Folder window opens in the content pane.
3. Select Data Replication Options.
The Data Replication Options window opens.
4. Select Set Data Replication Protocol.
The Data Replication Protocol options window opens.
5. Select HP FC Data Replication Protocol.
6. Select Save Changes.
Controller logs possibly retrieved incorrectly after upgrading to XCS 09534000 on the EVA4400
After upgrading the EVA4400 to XCS 09534000, HP Command View EVA might not retrieve the
controller logs correctly. This occurs if the controller event log sequence number is reset to zero
during the upgrade. When the controller logs are not being retrieved, controller log-related entries
will not be sent to the Windows application event log nor will the related WEBES callouts and
SNMP traps be sent.
To determine if this issue has occurred after the upgrade, access the HP Command View EVA GUI
and select View events > Controller Event Log. Compare the most recent value in the Sequence #
box in the GUI to the values in the \Program Files\Hewlett-Packard\Sanworks\Element
Manager for StorageWorks HSV\cache\[EVA WWN]\[EVA
