[Classification] ERROR
[Explanation] The specified pair cannot be registered in the AT-group.
To register a pair in an AT-group, the following conditions are required:
- The AT-group sync state is separated (Separated), failure separation (Fault),
or no pair registered (Invalid).
- The pair sync state is separated (separated), forced separate (cancel), or
failure separate (fault).
- The configuration of the pair must be RDR configuration. RV in RDR
configuration paired with MV must be only one.
- MV must be the top (PV) in relation with the related pairs, and it must not be
paired with another MV as RV.
- Every MV of RDR configuration within the AT-group must belong to the
same disk array.
- Every RV of RDR configuration within the AT-group must belong to the
same disk array.
- The number of pairs registered in the AT-group must not exceed the limit
(disk array specifications).
aaa...a : Volume name
bbb...b : AT-group name
ccc...c : Process number
ddd…d : Detailed information (This code is not disorder reason but a
value for maintenance.)
[Measures] Check the state of the AT-group, the state of the specified pair, and configuration
of the pair, and then re-execute the command. If the number of pairs registered
in the AT-group has already reached the limit, a new pair cannot be registered
any more.
