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 change default SAN provider values. You can change the default timeout values and other behaviors of the Site Recovery Manager SAN provider.

About this task

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

Procedure

  1. In the vSphere Web Client, click Site Recovery > Sites, and select a site.
  2. On the Manage tab, click Advanced Settings.
  3. Click Storage Provider.
  4. Click Edit to modify the storage provider settings.

    Option

    Action

    Make Site Recovery Manager attempt to detach and reattach LUNs with duplicate volumes. The default value is true.

    Select the storageProvider.autoDetachLUNsWithDuplicateVolume check box.

    Set the LVM.EnableResignature flag on ESXi hosts during test and recovery. The default value is 0.

    In the storageProvider.autoResignatureMode text box, enter 0 to disable, 1 to enable, or 2 to ignore the flag. The default setting is 0. If you set this flag to 1, Site Recovery Manager resignatures all known VMFS snapshot volumes, including any volumes that Site Recovery Manager does not manage. If you leave the flag set to 0, Site Recovery Manager only resignatures the VMFS snapshot volumes that it manages.

    Change the timeout in seconds to wait for Batch Attach LUN operation to complete on each ESXi host. The default value is 3600 seconds.

    Enter a value in the storageProvider.batchAttachTimeoutSec text box.

    Change the timeout in seconds to wait for Batch Detach LUN operation to complete on each ESXi host. The default value is 3600 seconds.

    Enter a value in thestorageProvider.batchDetachTimeoutSec text box.

    Change the interval that Site Recovery Manager waits for VMFS volumes to be mounted. The default value is 3600 seconds.

    Enter a new value in the storageProvider.batchMountTimeoutSec 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 5.5.1 and later.

    Change the interval that Site Recovery Manager waits for VMFS volumes to be unmounted. The default value is 3600 seconds.

    Enter a new value in the storageProvider.batchUnmountTimeoutSec text box. Change this value if you experience timeouts caused by Site Recovery Manager checking for VMFS volumes that take a long time to unmount. This setting is available in Site Recovery Manager 5.5.1 and later.

    Set number of retries for batch unmount of VMFS/NFS volumes. The default is 3 tries.

    Enter a new value in the storageProvider.datastoreUnmountRetryCount text box.

    Change the interval that Site Recovery Manager waits before attempting to unmount the datastore. The default is 1 second.

    Enter a new value in the storageProvider.datastoreUnmountRetryDelaySec text box.

    Force removal, upon successful completion of a recovery, of the snap-xx prefix applied to recovered datastore names. The default value is false.

    Select the storageProvider.fixRecoveredDatastoreNames check box.

    Change the time that Site Recovery Manager waits before removing the snap-xx prefix applied to recovered datastore names. The default value is 0 seconds.

    Enter a new value in the storageProvider.fixRecoveredDatastoreNamesDelaySec text box.

    Delay host scans during testing and recovery. The default value is 0 seconds.

    SRAs can send responses to Site Recovery Manager before a promoted storage device on the recovery site is available to the ESXi hosts. When Site Recovery Manager receives a response from an SRA, it rescans the storage devices. If the storage devices are not fully available yet, ESXi Server does not detect them and Site Recovery Manager does not find the replicated devices when it rescans. Datastores are not created and recovered virtual machines cannot be found.

    To delay the start of storage rescans until they are available on the ESXi hosts, enter a new value in the storageProvider.hostRescanDelaySec text box.

    Only change this value if you experience problems with unavailable datastores.

    Repeat host scans during testing and recovery. The default value is 1.

    Enter 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. In previous releases, you might have used the storageProvider.hostRescanRepeatCnt parameter to introduce a delay in recoveries. Use the storageProvider.hostRescanDelaySec parameter instead.

    Change the interval that Site Recovery Manager waits for each HBA rescan to complete. The default value is 300 seconds.

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

    Set the number of times that Site Recovery Manager attempts to resignature a VMFS volume. The default value is 1.

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

    Set a timeout for resignaturing a VMFS volume. The default value is 900 seconds.

    Enter a new value in the storageProvider.resignatureTimeoutSec text box. If you change the storageProvider.hostRescanTimeoutSec setting, increase the storageProvider.resignatureTimeoutSec setting to the same timeout that you use for storageProvider.hostRescanTimeoutSec.

    Identify VMX file paths that Site Recovery Manager should not consider as potential VMX file candidates after Storage vMotion. The default value is .snapshot,

    Some arrays create VMX file paths that the storageProvider.storageVmotionVmxSearch search algorithm should ignore. Enter a comma-separated list of strings in the storageProvider.storageVmotionVmxFilePathsToSkip text box to identify VMX file paths to ignore after Storage vMotion. Site Recovery Manager does not consider VMX file paths that contain one or more of these strings as potential candidate VMX files after Storage vMotion.

    Search for VMX files in recovered datastores to identify virtual machines that Storage vMotion has moved before or during a test or a recovery. The default value is true.

    The option is selected by default. Deselect the storageProvider.storageVmotionVmxSearch check box to disable this option.

    Set the timeout in seconds to wait for newly discovered datastores to become accessible. The default value is 60 seconds.

    Enter the new value in the storageProvider.waitForAccessibleDatastoreTimeoutSec text box.

    Enable Site Recovery Manager to wait to discover datastores after recovery.

    Select the storageProvider.waitForDeviceRediscovery check box.

    Set the timeout in seconds to wait for the Virtual Center to report newly discovered datastores. The default value is 30 seconds.

    Enter the new value in the storageProvider.waitForRecoveredDatastoreTimeoutSec text box.

    Set the time interval in seconds that Site Recovery Manager waits for VMFS volumes to become mounted. The default value is 30 seconds.

    Enter the new value in the storageProvider.waitForVmfsVolumesMountedStateTimeoutSec text box.
