Fault
Symptom
Handling Procedure Quick Recovery Method
A "Disk
Fault"
alarm is
reported
to iMana
200 or
iBMC.
1. If the drive is in a RAID array
and the RAID array is not
functioning correctly,
troubleshoot the RAID array.
2. If the server has stopped, use
Smart Provisioning to inspect
the server hardware. If the
server is operating, replace the
drive.
3. If the fault persists, insert the
new drive into the slot that
you suspect to be faulty to
check whether that slot is
faulty.
NOTE
For RAID controller cards that
support out-of-band
management, if a hard drive is in
the
Uncongured Good
(Foreign) state, an iBMC alarm
will be generated but the fault
indicator will be
o.
1. If the faulty drive is not in a
RAID array (except drives in
passthrough mode), the
drive cannot be used and
needs to be replaced. It is
recommended that you
congure RAID for all drives
and then deploy the
redundant services.
2. Back up the data of
redundant RAID arrays to
avoid data loss.
3. Follow the handling
procedure to replace any
faulty modules.
A RAID
controller
card fails
to identify
one or
more
drives.
1. Power o the server, swap the
drive that cannot be identied
with a normal drive, and
power on the server to check
whether the drive is faulty.
● If the fault is caused by the
drive, replace the drive.
● If the fault is caused by the
drive slot, check whether
SAS cables are connected
properly to all SAS ports on
the drive backplane. For
details, see the server user
guide.
● If the fault persists, go to 2.
2. Replace the RAID controller
card
rst, the SAS cables
second, and the drive
backplane third.
1. If the redundant RAID array
fails or no RAID array is
congured, the related drive
partitions are unavailable.
2. Move the unidentied drives
or all drives in the RAID
array to a standby server.
Ensure that you retain their
order during this process
and attempt to back up
data.
3. Follow the handling
procedure to replace any
faulty modules.
