F5 r10000/r12000 Series platforms include two solid-state drives (SSDs) that are configured with RAID enabled. In the event of a drive failure, F5 sends you a new replacement drive for the faulty drive. For these platforms you do not need to power down the system when replacing a drive as part of routine maintenance or in the event of a drive failure.
Replacement drives provided by F5 do not come pre-installed with software.
When performing a storage drive replacement, you must remove the failed drive from the software RAID array before physically removing the drive from the chassis.
