System information

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