perccli /cx/vx show erase
This command shows the progress of drive's security configuration and erases data in percentage.
Input example:
perccli /c0/v1 show erase
perccli /cx/vx stop erase
This command stops the erase operation.
Input example:
perccli /c0/v1 stop erase
perccli /cx/vx start erase [simple | normal | thorough | standard | threepass]
[patternA=<val>] [patternB=<val>]
This command securely erases virtual drives. The drive is written with erase patterns to ensure that the data is securely erased.
You can use the following options with the start erase command:
Table 16. Virtual drive erase command options
Options Value range Description
cx/vx
—
● /cx: specifies a controller where X is the
controller index.
● /vx: specifies the virtual drive where X is the
virtual drive ID.
erase
● simple: Single pass, single pattern write
● normal: Three pass, three pattern write
● thorough: Nine pass, repeats the normal
write three times
● threepass: Threepass, pass1 random pattern
write, pass 2, 3 write zero, verify
Secure erase type
patternA
8-bit value Erase pattern A to overwrite the data.
patternB
8-bit value Erase pattern B to overwrite the data.
NOTE: patternA and patternB are 8 bit binary values, that can be defined by the user. It should be used with
conjunctions with one of the secure erase types like simple, normal, thorough, standard, or pass.
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.
