Message
Explanation
Action
Configured
drives are
missing.
When the ServeRAID controller detects
that a previously configured drive is
missing, the following message
appears:
x
Online drive(s) not responding
or found at new location(s)
where
x
is the number of drives not
responding.
After pressing F2, a more detailed
message appears:
Online Drive on Channel
x
SCSI
ID y is not responding.
where
x
is the channel ID and
y
is the
SCSI ID.
Press one of the following keys:
F2
Detailed description. Press this key for a detailed
description of the problem.
F4
Retry. Press this key after correcting a problem.
For example, press F4 after you turn on the
external storage enclosure that contains the
physical drive.
F5
Change the configuration and set the drives to
defunct. Press this key to accept the new state
that the ServeRAID controller will assign to the
drive. For example, the ServeRAID controller will
assign the drive a state of defunct or empty.
You also can press F5 when you must remove a
drive. RAID level-1 and RAID level-5 logical
drives are present, and performance in a
degraded mode is acceptable. The ServeRAID
controller will assign the drive a state of defunct,
but the server can complete startup. However, the
array will remain in the critical state and the
potential for data loss will exist until you replace
and rebuild the defunct drive. To prevent the loss
of data, replace and rebuild the defunct drive in a
timely manner.
Note:
A physical drive in the defunct state does
not necessarily mean that you need to replace
the drive. Before you replace the drive, ensure
that:
1. All cables are connected properly to the
backplane and to the physical drive. Also,
ensure that all cables inside the server are
connected properly.
2. The hot-swap drive trays are seated properly
in the drive bay.
3. If multiple drives fail in separate arrays (one
physical drive per array), replace each of the
defunct physical drives. If multiple physical
drives fail at the same time within the
same
array, contact your IBM service
representative. See “Rebuilding a defunct
drive” on page 157 for more information.
After you perform these steps, if the physical
drive does not function properly, replace the drive.
F10
Continue starting without changing the
configuration. Press this key to continue without
change to the configuration.
