Change Storage Provider Settings

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.
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.
  1. In the
    vSphere Client
    , click
    Site Recovery
    Open Site Recovery
    .
  2. On the
    Site Recovery
     home tab, select a site pair, and click
    View Details
    .
  3. In the left pane, click
    Configure
    Advanced Settings
    Storage Provider
    .
  4. Select a site, and 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.
    Move the slider to change the value of
    storageProvider.autoDetachLUNsWithDuplicateVolume
    .
    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 deactivate,
    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 the
    storageProvider.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.
    Change the time in seconds to wait before fetching datastores on the
    ESXi
     hosts after receiving an SRA response during test and recovery. This setting applies only when there are no SCSI devices. The default value is 0.
    Enter a new value in the
    storageProvider.fetchDatastoreDelaySec
     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.
    Move the slider to change the value of
    storageProvider.fixRecoveredDatastoreNames
    .
    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.
    Change the time interval between SMP-FT VM datastore compliance checks. The default value is 300 seconds.
    Enter a new value in the
    storageProvider.ftVmComplianceCheckInterval
     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,
    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.
    Set the timeout in seconds for local stretched devices to be matched to the corresponding remote stretched devices. The default is 300 seconds.
    Enter the new value in the
    storageProvider.stretchedDevicesMatchTimeout
     text box.
    Set the number of parallel xVC-vMotion requests per host. This limit applies to both source and target hosts. The default value is 2.
    Enter the new value in the
    storageProvider.vmMigrationLimitPerHost
     text box.
    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.
    Set
    Site Recovery Manager
     to wait to discover datastores after recovery. The default value is false.
    Move the slider to change the value of
    storageProvider.waitForDeviceRediscovery
     to true.
    Set
    Site Recovery Manager
     to wait to discover datastores after failover. The default value is true.
    Move the slider to change the value of
    storageProvider.waitForDeviceRediscoveryAfterPrepareFailover
     to false.
    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.
