Replacing hard disks during ong
oing operation
Fujitsu Technology Solutions reject s any responsibility with re gard to product
damage/malfunctions or data loss/recovery due to incorrect use o r improper
installation of hard disks for any reason.
Please note that a hard disk (new or used), which has not yet be en installed in the NAS,
will be automatically formatted and partitioned; all data on the hard disk will be lost.
The N AS supports the replacement of h ard disks during ongoing o peration if a hard disk
fails in RAID 1 or one to two hard disks in RAID 5 or 6 fail.
However, to completely eliminate the risk of electric sho ck, Fujitsu Technology
Solutions recommends switching off the NAS before replacing hard disks.
To replace a hard disk during ongoing operation, proceed as follows:
Have a new hard disk ready to replace the faulty hard disk.
The capacity of the new hard disk should be the same as or greater
than the capacity of the faulty hard disk.
► LogintotheNAS.
► Check the drive
configuration under Storage Manager.
► The drive is in degraded mode.
► Disconnect th
e faulty hard disk from the NAS.
► Wait until the server emits two beeps.
► Remove the fa
ulty hard disk from the carrier.
► Insert the ne w hard disk in the carrier.
► Insert the c
arrier in the NAS .
► The server should emit two 1.5 second beeps.
► Check the d
rive status on the web administration page.
The drive now automatica lly executes the r estore.
