For array-based replication, the SAN provider is the interface between Site Recovery Manager and your storage replication adapter (SRA). Some SRAs require you to make changes to default SAN provider values. You can change the default timeout values and other behaviors of the Site Recovery Manager SAN provider.

You can change settings for resignaturing, fixing datastore names, host rescan counts, and timeouts. For more information about these values, see the SRA documentation from your array vendor.

Option

Action

Make Site Recovery Manager attempt to detach and reattach LUNs with duplicate volumes

Select the storageProvider.autoDetachLUNsWithDuplicateVolume check box.

Set the LVM.EnableResignature flag on ESXi hosts during test and recovery

In the storageProvider.autoResignatureMode text box, type 0 to disable, 1 to enable, or 2 to ignore the flag. The default setting is 1, and Site Recovery Manager resignatures all known VMFS snapshot volumes, including any volumes that Site Recovery Manager does not manage. If you set the flag to 0, Site Recovery Manager only resignatures the VMFS snapshot volumes that it manages, but this might result in slower performance, leading to timeouts.

Force removal, upon successful completion of a recovery, of the snap-xx prefix applied to recovered datastore names

Select the storageProvider.fixRecoveredDatastoreNames check box.

Repeat host scans during testing and recovery

Type a new value in the storageProvider.hostRescanRepeatCnt text box. Some storage arrays require more than one rescan, for example to discover the snapshots of failed-over LUNs.

Change the interval that Site Recovery Manager waits for each HBA rescan to complete

Type a new value in the storageProvider.hostRescanTimeoutSec text box.

Set the number of times that Site Recovery Manager attempts to resignature a VMFS volume

Type a new value in the storageProvider.resignatureFailureRetryCount text box.

Change the interval that Site Recovery Manager waits for recovered datastores to become accessible

Type a new value in the storageProvider.waitForAccessibleDatastoreTimeoutSec text box. Change this value if you experience timeouts caused by Site Recovery Manager checking for datastores that are not available yet. This setting is available in Site Recovery Manager 5.1.2 and later.

Change the interval that Site Recovery Manager waits for recovered datastores to be added to vCenter Server

Type a new value in the storageProvider.waitForRecoveredDatastoreTimeoutSec text box. Change this value if you experience timeouts caused by Site Recovery Manager checking for datastores that have not been detected by vCenter Server yet. This setting is available in Site Recovery Manager 5.1.2 and later.

Change the interval that Site Recovery Manager waits for VMFS volumes to be mounted

Type a new value in the storageProvider.waitForVmfsVolumesMountedStateTimeoutSec text box. Change this value if you experience timeouts caused by Site Recovery Manager checking for VMFS volumes that take a long time to mount. This setting is available in Site Recovery Manager 5.1.2 and later.
