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
DriveSizeIncrement is measured in megabytes.
sdcli disk expand -z 1024 -d p
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.)
