Managing Synchronous Mirroring
The Synchronous Mirroring feature (also referred to as RVM) is supported only for Fibre Channel.
About this task
If you are currently using Synchronous Mirroring and want to change from Fibre Channel to any other protocol, you must delete
any synchronous mirrored pairs and deactivate any synchronous mirroring relationships.
Attention:
If you do not deactivate these relationships before upgrading the HICs, your system loses data access and data loss
might occur.
Steps
1. In the Array Management Window, select Help > Contents, and search for the topics related to Synchronous Mirroring.
2. Follow the instructions in the online help to identify all synchronous mirroring volumes that might exist.
3. In the Logical pane, right-click a synchronous mirroring volume, and select Copy Services > Synchronous Mirroring >
Remove Mirror Relationship.
4. Select all volumes, and click Remove.
5. After you delete all mirroring relationships, deactivate Synchronous Mirroring by selecting Copy Services > Mirroring >
Deactivate.
6. Select the synchronous mirroring check box from the pop-up window.
Attention:
If you do not delete all mirroring relationships before deactivating mirroring, you receive an error.
Managing Asynchronous Mirroring
The Asynchronous Mirroring feature (also referred to as ARVM) is supported only for iSCSI and Fibre Channel.
About this task
If you are currently using asynchronous mirroring relationships and want to change the protocol to IB or SAS, you must delete
the mirrored pairs and deactivate the asynchronous mirroring relationships.
Steps
1. In the Array Management Window, access the online help and search for the topics related to Asynchronous Mirroring.
2. Follow the instructions in the online help to remove all asynchronous mirrored pairs from the asynchronous mirror groups.
Note:
When removing each pair, select the Delete all repositories associated with this mirrored pair check box.
3. Follow the instructions in the online help to delete all asynchronous mirror groups.
Cabling considerations
Before upgrading hardware, confirm that your replacement cables and any SFPs or QSFPs are compatible with the connectors
on the new HICs.
The following table lists the supported cables for E5600 and EF560 HICs:
