Disaster reco

very 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}-ttimeout-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
