Dell Storage Manager configuration

18 Dell EMC SC Series: VMware Site Recovery Manager Best Practices | 2007-M-BP-V

making adjustments to accommodate such environments, see VMware KB article, Modify Settings to Run

Large Site Recovery manager Environments.

• storage.commandTimeout – Min: 0 Default: 300

This option specifies the timeout allowed (in seconds) for running SRA commands in array-based-

replication-related workflows. Increasing this value is typically required for larger environments or

environments with Live Volume stretched storage. Recovery plans with a large number of datastores

to manage may fail if the storage-related commands take longer than five minutes to complete. For

larger environments, increase this value (for example, to 3600 or higher) in the advanced SRM

settings. For environments including Live Volume stretched storage within protection groups, this

value should be increased by 90 seconds for each Live Volume managed by SRM.

• storage.maxConcurrentCommandCnt – Min: 0 Default: 5

This option specifies the maximum number of concurrent SRA operations allowed.

• storageProvider.hostRescanRepeatCnt – Min: 0 Default: 1

This option specifies the number of additional host rescans during test, planned migration, and

recovery workflows. This feature was not available in SRM 5.0 and was re-introduced in SRM 5.0.1.

Increase this value (for example, to 2 or higher) in the advanced SRM settings.

• storageProvider.hostRescanTimeoutSec – Min: 0 Default: 300

This option specifies the timeout allowed (in seconds) for host rescans during test, planned migration,

and recovery workflows. Recovery plans with a large number of datastores and/or hosts will fail if the

host rescans take longer than five minutes to complete. Increase this value (for example, to 600 or

higher) in the advanced SRM settings.

• storageProvider.stretchedDevicesMatchTimeout – Min: 0 Default 300

This option specifies the timeout allowed (in seconds) for local stretched devices to be matched to the

corresponding remote stretched devices. Increase this value (for example, to 1000 or higher) in the

advanced SRM settings. Increasing this value is typically required for environments including Live

Volume stretched storage within protection groups.

• defaultMaxBootAndShutdownOpsPerCluster – Default: off

This option specifies the maximum number of concurrent power-on operations performed by SRM at

the cluster object level. Enable the option globally by specifying a numerical value (such as 32) by

modifying the vmware-dr.xml file. The option can be added anywhere in the <config> section and the

Site Recovery Manager Server service should be restarted after making a change.
