Recommendations for clearing Bad Blocks

About this task

Storage Management allows you to clear the bad block warnings. To clear bad blocks, the following procedure is recommended:

Steps

  1. Perform a backup of the virtual disk with the Verify option selected.

    One of the following scenarios may occur:

    • Backup operation fails on one or more files. In this case, restore the file from a previous backup. After restoring the file, proceed to step 2.
    • Backup operation completes without error. This indicates that there are no bad blocks on the written portion of your virtual disk.

    If you still receive bad block warnings, the bad blocks are in a non-data area. Proceed to step 2.

  2. Run Patrol Read and check the system event log to ensure that no new bad blocks are found.

    If bad blocks still exist, proceed to step 3. If not, the condition is cleared without the need for step 3.

  3. To clear these bad blocks, execute the Clear Virtual Disk Bad Blocks task.

    This Clear Virtual Disk Bad Block feature is applicable to PERC H730P MX and PERC H745P MX.
