Figure 76 Overview of remote copy operations

Starting CA XP Journal ops. and creating CA XP Journal pairs

If the Continuous Access XP Journal S-VOL contains a ﬁle system, you must delete the ﬁle system using

the enas_fsdelete command in NAS Blade Manager before starting Continuous Access XP Journal

operations. Also, if you use the Continuous Access XP Journal S-VOL for the Snapshot feature in NAS

BackupRestore,youmustdeletetheSnapshotdeﬁnitions using the snapvoldel command before starting

Continuous Access XP Journal operations. If the differential-data storage device of NAS Sync Image is

in the Continuous Access XP Journal S VOL, you must release it using the syncstop command before

starting Continuous Access XP Journal operations.

To start Continuous Access XP Journal operations and create a Continuous Access XP Journal volume pair:

1. At the primary and secondary sites, start RAID Manager XP.

sudo horcmstart.sh (1-instance conﬁguration)

sudo horcmstart.sh 16 17

2. At the secondary site, reserve the device ﬁle used as a target ﬁle system.

•Non-LVM:

sudo horc_svol_deﬁne -d Device ﬁle number

•LVM:

sudo horc_svol_vmdeﬁne -d Device ﬁle number,...

3. At the primary site, create a Continuous Access XP Journal volume pair.

sudo paircreate {-g group-name|-d volume-name} -f {never|async} -vl -jp master journal group ID

-js restore journal group ID

4. At the primary site, check the completion of the Continuous Access XP Journal volume pair creation.

sudo pairvolchk {-g group-name|-d volume-name}

NOTE:

You can also use the pairevtwait command, which waits for the volumes to be paired.

pairvolchk: Volstat is P-VOL.[status = COPY] => Creating

pairvolchk: Volstat is P-VOL.[status = PAIR] => Created
