Secure data deletion for drives attached with Broadcom (LSI) MegaRAID 9361-8i SAS3 Controller

Edit online

You can use the Linux commands to securely delete data from the drives that are attached with Broadcom (LSI) MegaRAID 9361-8i SAS3 Controller.

Note: If the drives on which you are performing the secure data deletion are attached to an Broadcom (LSI) MegaRAID 9361-8i SAS3 Controller, consider the following requirements:
  • Use only the storcli command to securely delete data for drives.
  • Drives must be removed from virtual disks (VDs) and just a bunch of drives (JBODs).
  • The output of the show command displays the drive IDs and the status of self-encrypting drives (SEDs).
To securely delete data for drives that are attached with Broadcom (LSI) MegaRAID 9361-8i SAS3 Controller, choose one of the following options depending on the type of the drive:
  • To securely delete data for self-encrypting drives (SEDs), run the following command:
    storcli /cx/ex/sx secureerase [force]
  • To securely delete data for drives other than self-encrypting drives, you can run one of the following commands depending on whether the drive supports the crypto-erase operation:
    • To securely delete data for the drive that supports crypto-erase operation, run the following command:
      storcli /cx/ex/sx start erase crypto
    • To securely delete data for the drive that does not support crypto-erase operation, run one of the following commands depending on the type of erase operation that you want to perform:
      • storcli /cx/ex/sx start erase simple patternA=X patternB=Y
      • storcli /cx/ex/sx start erase normal patternA=X patternB=Y
      • storcli /cx/ex/sx start erase thorough patternA=X patternB=Y

      Where, X and Y are 8-digit binary numbers.

Notes:
  • If the secure delete operation takes a longer time, to check the status of the operation, run the following command:
    storcli /cx/ex/sx show erase
  • If the secure delete operation is run on multiple drives, check the status of all operations by running the following command:
    storcli /cx/eall/sall show erase
