Disaster recovery operations

This section describes procedures for disaster recovery operations. You might also want to refer to

Settings for disaster recovery

.

Switching operations to the secondary site

To recover data from a disaster:

1.

Execute SVOL-Takeover using the horctakeover command.
sudo horctakeover {-g group-name|-d volume-name} -t timeout-period

2.

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, ...

3.

Mount the S-VOL using the enas_fsmount command, and create CIFS/NFS shares using the

enas_nfscreate and enas_cifscreate commands.
Recover the file system when mounting the S-VOL.

4.

Start the program that accesses the S-VOL.

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.

Transferring data back to the primary site

To transfer data back to the primary site:

1.

At the primary site, set up the environment variable of the RAID Manager XP instance:
sudo horc_setenv HORCMINST 16 (for instance number 16)
sudo horc_setenv HORCMINST 17 (for instance number 17)

2.

At the primary site, set up the HOMRCF command environment variable of RAID Manager XP as

Continuous Access XP Journal:
sudo horc_unsetenv HORCC_MRCF

3.

After logging in to the target NAS package using SSH and setting up as explained in Step 1 and

Step 2, confirm the setup by logging out of the NAS package and relogging in.
exit
