Notes on operations of RAID Manager XP log files
Since RAID Manager XP log files are output to NAS OS LU, if Continuous Access XP Journal operations still
show an error, log files become large and available space on NAS OS LU decreases. You should
periodically check the capacity of log files (except trace files) to which RAID Manager XP restricts capacity,
stop RAID Manager XP, and delete log files using the
horc_logremove
command before exceeding
1 MB. Check the log files’ capacity using the following command.

Notes on failures of external volumes
If a problem (including a temporary problem, for example, the cable connection cut out) occurs to the
external volume that is currently used with Continuous Access XP Journal volume pair, perform the following
processes:
1. If the external volume cannot be used successfully, delete the Continuous Access XP Journal volume pair
using the
pairsplit -S
command.
If the S-VOL is not connected to the NAS package, release the device file used in the target file system
using the
horc_svol_delete
(non-LVM) or
horc_svol_vmdelete
(LVM) command.
2. Confirm all Continuous Access XP Journal volume pair statuses that are using the external volume with
problems using the
pairdisplay
command.
If the status of the Continuous Access XP Journal volume pair is PSUE, delete the volume pair using the
pairsplit -S
command.
