8. Hot plug Drive Replacement
In the event of a drive failure, the RAID subsystem supports the ability to hot-swap drives
without powering down the system. A disk can be disconnected, removed, or replaced with a
different disk without taking the system off-line. In a fault tolerant array, the RAID rebuilding
will proceed automatically in the background (see chapter 5, “Understanding RAID” for more
information.)
A drive failure will illuminate amber the Disk Activity/Fault LED on the affected drive canister.
To replace a drive, please follow these steps:
1. Make sure the drive locking mechanism (see page 9, “The MaxNAS Interface components”)
is in the up-down position (use the included key to turn the mechanism.)
2. Click down on the drive release latch (see page 9, “The MaxNAS Interface components”) to
release the drive tray.
3. Gently pull out the disk drive tray handle and slide out the drive tray.
4. To replace: Slide in the replacement drive tray with the tray handle open. When the tray is
slid all the way into the MaxNAS, push the tray handle closed.
IMPORTANT: NEVER remove a drive tray without replacing it. Operating the RAID with a drive tray
missing will disrupt airflow and may cause the MaxNAS to fail.
