Virtual drive migration commands

NOTE: The virtual drive migration commands are not supported in Embedded MegaRAID.

The PERC Command Line Tool supports the following commands for virtual drive migration (reconstruction):

perccli /cx/vx show migrate
perccli /cx/vx start migrate type=raidx [option=add|remove drives=[e:]s|[e:]s-x|[e:]s-x,y][Force]  

The detailed description for each command follows.

perccli /cx/vx show migrate

This command shows the progress of the virtual drive migrate operation in percentage.

Input example:

perccli /c0/v0 show migrate

perccli /cx/vx start migrate type=raidx [option=add|remove drives=[e:] s| [e:]s-x| [e:]s-x,y] [Force]

This command starts the reconstruction on a virtual drive to the specified RAID level by adding or removing disks from the existing virtual drive. You can use the following options with the start migrate command:
