The disk expand command expands the disk by a user-specified size, as long as that figure falls within the SnapDrive-specified minimum and maximum values.
sdcli disk expand [-m MachineName] {-p LUNpath | -d MountPoint} -z DriveSizeIncrement [-rs Reserve Snapshot copy space {y|n}]
-z DriveSizeIncrement is the amount by which you want to expand the disk. You can specify a postfix of MB, GB, or TB. If no postfix is specified, the default is MB.
-rs enables you to limit the maximum disk space for the disk you are expanding to allow for at least one Snapshot copy on the volume. This option is recommended.
sdcli disk expand -d p -z 1GB
The preceding example increases the LUN mapped to “P:” by 1 GB. (In practice, SnapDrive expands the disk by the amount specified by -z, plus a certain increment required for system overhead.)
sdcli disk expand -d C:\ClusterStorage\Volume8 -z 100
The preceding example expands a CSV disk by 100 MB on the CSV reparse point C:\ClusterStorage\Volume8.
