7.
At the primary site, mount the P-VOL using the
enas_fsmount
command in NAS Blade
Manager, and create CIFS/NFS shares using the
enas_nfscreate
and
enas_cifscreate
commands.
8.
At the primary site, restart the program that accesses the P-VOL.
9.
At the secondary site, connect the target file system to the NAS package.

10. At the secondary site, mount the S-VOL using the
enas_fsmount
command. Create a shared
directory using the
enas_dircreate
command, or change the attributes of a shared directory
using the
enas_diredit
command. Create CIFS/NFS shares using the
enas_nfscreate
and
nas_cifscreate
commands.
NOTE:
When the S-VOL is the file system managed by NAS/Sync Image, mount the
differential-data snapshots using the
syncmount
command, and create the CIFS/NFS shares
using the
enas_nfscreate
and
enas_cifscreate
commands, if necessary.
11. At the secondary site, start the program that accesses the S-VOL.
Online backup
To split the XP Continuous Access Journal volume pair with online backup:
1.
At the primary site, prevent NAS Sync Image from performing operations on the P-VOL, hold
the write request to the P-VOL, and write the unapplied data to the disk.
sudo horc_pvol_freeze -f
Source-file-system-name
2.
At the primary site, split the XP Continuous Access Journal volume pair.
sudo pairsplit {-g
group-name
|-d
volume-name
} -rw
3.
At the primary site, verify that the XP Continuous Access Journal volume pair has been split.
sudo pairvolchk {-g
group-name
|-d
volume-name
}
NOTE:
You can also use the
pairevtwait
command, which waits for the pair to be split
(PSUS).
pairvolchk : Volstat is P-VOL.[status = COPY] => Splitting
pairvolchk : Volstat is P-VOL.[status = PSUS] => Split completes
4.
At the primary site, permit the write request to the P-VOL, and enable the operations from NAS
Sync Image on the P-VOL.
sudo horc_pvol_unfreeze -f
Source-file-system-name
5.
At the secondary site, connect the target file system to the NAS package.
