172 Continuous Access XP Journal operations with NAS Blade
To resynchronize the Continuous Access XP Journal volume pair:
1. At the secondary site, reserve the device file to be used as a target file system
• Non-LVM:
?sudo horc_svol_define -d Device-file-number
• LVM:
?sudo horc_svol_vmdefine -d Device-file-number, ...
2. At the primary site, resume the Continuous Access XP Journal volume pair.
sudo pairresync {-g group name|-d volume name}
3. At the primary site, verify that the Continuous Access XP Journal volume pair has been resumed.
sudo pairvolchk {-g group name|-d volume name}
NOTE: You can also use the
pairevtwait
command, which waits for the volumes to be paired.
pairvolchk: Volstat is P-VOL.[status = COPY] => Resuming
pairvolchk: Volstat is P-VOL.[status = PAIR] => Resuming completes
Deleting Continuous Access XP Journal volume pairs
Completing Continuous Access XP Journal operations by deleting the Continuous Access XP Journal volume
pair in PSUS status differs depending upon whether you will continue using the file system in the S-VOL or
if you will destroy the file system.
When deleting the Continuous Access XP Journal volume pair in a status other than PSUS, you cannot use
that file system because the consistency of data in the S-VOL is not guaranteed.
To delete the Continuous Access XP Journal volume pair in PSUS status and continue using the S-VOL file
system:
1. At the primary site, delete the Continuous Access XP Journal volume pair.
sudo pairsplit {-g group name|-d volume name} -S
2. At the primary site, verify that the Continuous Access XP Journal volume pair has been deleted.
sudo pairvolchk {-g group name|-d volume name}
pairvolchk: Volstat is P-VOL.[status = COPY] => Deleting
pairvolchk: Volstat is P-VOL.[status = SMPL] => Deleted
3. At the primary and secondary sites, stop RAID Manager XP.
sudo horcmshutdown.sh
(1-instance configuration)
sudo horcmshutdown.sh 16 17
(2-instance configuration)
NOTE: If you start the split pair operation with offline backup, but have not yet connected the target file
system to the NAS package at the secondary site, finish connecting the target file system to the NAS
Package, and then start the previously described operations. If you start the split pair operation with online
backup, but do not connect the target file system to the NAS package at the secondary site, finish
connecting the target file system to the NAS Package, and then start the previously described operations
(see ” Splitting Continuous Access XP Journal volume pairs ” on page 170).
To delete the Continuous Access XP Journal volume pair in PSUS status without using the S-VOL file system:
1. At the secondary site, terminate the program that accesses the S-VOL.
2. At the secondary site, delete CIFS/NFS shares using the
enas_nfsdelete
and
enas_cifsdelete
commands, and unmount S-VOL using the
enas_fsumount
command.
