Disaster recovery operations

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

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 XP RAID Manager 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 XP RAID Manager

as XP Continuous Access Journal:

sudo horc_unsetenv HORCC_MRCF
