You should set the following timeout values on SRM for scaled environment:

Storage settings

When you hit a timeout, increase the values of storage.commandTimeout and storage.maxConcurrentCommandCnt to a higher value.

Note The timeout interval specified is the maximum value. You do not need to wait for the maximum timeout to be reached. Most commands finish within the set maximum timeout interval.

See the VMware documentation on modifying SAN Provider settings for more information.
