Switching from Raid1 to Raid10

  • 772

we are running a Dell Server with a PERC5i Raid card using a Raid1 setup. Now we are hitting a performance problem with our harddrive performance and think about switching to Raid10.

Which steps are necessary when switching from Raid1 to Raid10? Can I do this without a new installation of the system?

Thanks! Jonas

    1. Backup the server and test the backup
    2. Update the server - BIOs, PERC firmware, disk firmware - everything (contact Dell support for help with that)
    3. Go into OMSA (install OMSA if you don't have it - Dell support can provide a link)
    4. In OMSA go to the Logical Disk, from the drop down menu choose "reconfigure" and if you have enough drives, it will let you choose the additional disks and a new raid level.

    Plan for downtime - reconfig might take a while, and it's not recommended to do any data manipulation on the host during the reconfiguration.
