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. 12

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
