SRN Problem Possible Causes
48750 Description:An array is in the Offline state because the primary or the
secondary half of the array is not present.
Action: Switch on the power to the other half of the array,or repair the
broken loop that is preventing access to the other disk drives.
If the other half of the array has become permanently unavailable
because an unrecoverable error has occurred, you can force access to
the available half of the array.
Attention: Do not force access to the available half of the array unless
you are sure that no updates to the other (unavailable) half of the array
will be performed. See Chapter8, “Split-Site Management”on page193
before you perform this operation.
Toforce access to the available half of the array, change the setting of the
SplitArray Resolution flag:
1. Type smitty ssaraid and press Enter.
2. Select Change/Show Attributes of an SSA RAID Array.
3. Change the setting of the Split Array Resolution flag.
4. If possible, change the setting of the Split Array Resolution flag on the
unavailable half of the array.
Attention: If the unavailable half of the array is reconnected to the
available half before the setting of the SplitArray Resolution flag has
been changed, neither SSAadapter can get access to the array.
The adapter cannot get access
the other adapter in the loop
because one of the following
conditions exists:
vThe SSAadapter can detect
the secondary half of the
array,but the Split Array
Resolution flag is set to
Primary.
vThe SSAadapter can detect
the primary half of the array,
but the SplitArray Resolution
flag is set to Secondary.
This problem can be caused by
a power failure on one half of
the array,or by a broken SSA
loop between the two halves of
the array.
48755 Description: One of the following conditions exists:
vOne member of a RAID-1 array has been detected, but the adapter is
unknown to that array member.
vAll the primary,or all the secondary, disk drives of a RAID-10 array are
present, but the adapter is unknown to the array.
Action: If the problem has resulted from an unplanned change to the
using-system configuration, return the using system to its original
configuration.
If the problem has resulted from the failure of an SSAadapter and the
failure of half the members of an array,do the following actions to attach
the array to the adapter:
1. Type smitty ssaraid and press Enter.
2. Select Change/Show Attributes of an SSA RAID Array.
3. Change the setting of the Split Array Resolution flag.
The array becomes available, but remains in the Exposed state or the
Degraded state until the missing array members are added.
4. Add the missing members of the array:
a. Select Change Member Disks in an SSA RAID Array from the
SSARAID Arrays menu.
b. Select Add a Disk to an SSA RAID Array once for each disk
drive that you need to add to the array.
vAn SSAadapter and a pdisk
have failed.
vARAID member disk drive is
connected to another SSA
adapter.
vAsplit-site configuration has
only one SSAadapter
configured, and the adapter
and all the primary,or
secondary,disk drives fail.
