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.

• Non-LVM:

sudo horc_svol_import -f Target-file-system-name -d Device-file-number

• LVM:

sudo horc_svol_vmimport -f Target-file-system-name -d Device-file-number,

...

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.

• Non-LVM:

sudo horc_svol_import -f Target-file-system-name -d Device-file-number

• LVM:

sudo horc_svol_vmimport -f Target-file-system-name -d Device-file-number,

...

6. At the secondary site, mount the S-VOL using the enas_fsmount command.
