Explanation
During a FRBACKUP command, an insufficient number
of copy pool backup storage group volumes were available for the source
storage group volumes defined to the copy pool.
System action
The fast replication processing ends. DFSMShsm processing
continues.
Programmer response
Issue the SETSYS FASTREPLICATION(VOLUMEPAIRMESSAGES(YES))
command to enable the ARC1809I message. This will help you determine
why each copy pool backup volume was not selected.
The following
values are assigned to
variables listed in
this message:
- num1
- If num1 is less than the number
of copy pool backup versions multiplied by the number of volumes that
are defined in the source storage group, there are not enough target
volumes defined in the copy pool storage group.
- num2
- num2 — The number of volumes that were defined
in the copy pool backup storage group but were not fast replication
compatible with volume volser. The following are
possible reasons for the incompatibility:
- The volumes might be offline
- The volumes might be of a different device type
- The volumes might be in a different LSS (for FlashCopy® version 1 devices)
- The volumes might be in a different ESS
- num3
- num3 — The number of copy pool backup storage
group volumes that were rejected because they were not the same size
as the source volser.
- num4
- num4 — The number of copy pool backup storage
group volumes that have been paired with different copy pool storage
group source volumes.
