The Snap Configuration tab contains properties that affect the behavior of the storage array in your environment.
Property |
Description |
---|---|
Use Consistency Group |
Select this option to enable a consistency group, which reduces the time to verify the consistency of participating disks. By default, this option is selected. Tips
|
EMC SYMAPI Installation Home Directory Path |
The directory where the EMC SYMAPI library is located. Examples:
|
Remote Snap MA |
The client name of the MediaAgent that you want to designate as the Remote Snap MediaAgent. |
Enable VNX Snapshots |
Select this option to enable VNX snapshots. By default, this option is not selected. Note VNX snapshots are supported only for pool logical unit numbers (LUNs). |
EMC Navisphere CLI Installation Home Directory Path |
The directory where Navisphere CLI is located. Important This option is required for VNX snapshots. |
Delete Restore Point Snapshot |
Select this option to enable the deletion of Restore Point Snapshots after successful revert operations. Revert from VNX snapshots automatically creates a “Restore Point Snapshot”, to recover from accidental data corruption. By default, this option is not selected. |
Sync operation retry count |
The maximum number of times to attempt to synchronize a SYMAPI database. By default, the value is 10. |
Sync operation retry interval (in seconds) |
The time interval (in seconds) after which the next SYMAPI database synchronization operation is executed. By default, the value is 5. |
Maximum SnapView Sessions per LUN |
The maximum number of SnapView sessions per LUN. The limit is 8 sessions per LUN. You can specify any value between 1 and 8. |
Clone Sync Rate |
The speed of the synchronization. The values that you can enter for the mode are as follows:
Tip Follow the vendor's recommendation for the clone synchronization rate. |
Enable physical delete of clone |
Select this option to force the physical deletion of the clone during a delete operation. This option disables incremental clone operations. By default, during a delete operation, the clone is marked as aged and is not deleted. When a new clone request comes for the same LUN, the aged clone is selected for an incremental synchronization. |
Use EMC API to detect host device paths |
Select this option to enable the use of EMC APIs to detect Multipath I/O (MPIO) device paths. By default, this option is not selected. |
Powerpath Device cleanup retry count |
The number of times to attempt the powerpath device cleanup. By default, this value is 10. |
EMC Powerpath Installation Home Directory |
The path to the EMC powerpath installation directory. If you don't enter a path, then the commands that are executed during snapshot operations or clone operations might fail. |
Full sync during Rollback |
Select this option to force the full synchronization of the SYMAPI database during a rollback. By default, this option is not selected. |
Mount Retry Interval (in seconds) |
The time interval (in seconds) after which the next mount operation is attempted. The default value is 300 (5 minutes). |
Disable VNX Snapshot Auto-Delete |
Select this option to disable the VNX Snapshot Auto-Delete policy at the snapshot level. |
