我有一个 SSD,Kioxia 型号 KRM6VRUG1T92,位于配备 PERC H730P 的 Dell 服务器中,该服务器具有以下策略,如perccli64 /c0/e32/s0 show all
Linux 下所示:
FDE Type = None
SED Capable = Yes
SED Enabled = No
Secured = No
Cryptographic Erase Capable = Yes
Sanitize Support = Not supported
查看用于安全擦除驱动器的可用命令,我看到三个可能的命令。 perccli64 /c0/e32/s0 secureerase force
在此驱动器上工作,但start erase crypto
失败Start Drive erase is not allowed
并start sanitize cryptoerase
返回Sanitize is not supported on this controller
。
三个可能的命令:
NAME: Drive Instant Secure Erase
SYNTAX: perccli /cx[/ex]/sx secureerase [force]
DESCRIPTION: This command erases the drive's security configuration and securely
erases data on a drive.
OPTIONS:
force - Use the force option as a confirmation to erase.
NAME: Securely erases non-SED Drives
SYNTAX: perccli /cx[/ex]/sx start erase
[simple| normal| thorough| standard| threepass | crypto]
[patternA=<val>][patternB=<val>]
DESCRIPTION: Securely erases non-SED drives with specified erasepattern(s).
OPTIONS:
simple| normal| thorough| standard| threepass- erase types
simple - Single pass, single pattern write
normal - Three pass, three pattern write
thorough - Nine pass, repeats the normal write 3 times
standard - Applicable only for DFF's
threepass - Three pass, pass1 random pattern write, pass2,3 write zero, verify
crypto - Applicable only for ISE capable drives
PatternA|PatternB - an 8-Bit binary pattern to overwrite the data.
NAME: Sanitize the Drives
SYNTAX: perccli /cx[/ex]/sx start sanitize
< cryptoerase| overwrite| blockerase > [ause]
DESCRIPTION: Sanitize drives with specified pattern(s).
OPTIONS:
sanitize types:
cryptoerase - Keys gets corrupted on the drive.
overwrite - Overwritten by all zero's.
blockerase - Data is cleared by the drive.
ause - Allow Unrestricted Sanitize Exit.
这三种方法之间有什么区别,需要具备哪些驱动器或控制器特性才能运行它们?
