7.

Create a shared directory using the

enas_dircreate

command, or change the attributes

of a shared directory using the

enas_diredit

command.

8.

Create CIFS/NFS shares using the

enas_nfscreate

and

enas_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.

9.

At the secondary site, start the program that accesses the S-VOL.

Resynchronizing XP Continuous Access Journal volume pairs

You must delete the target file system using the

enas_fsdelete

command before resynchronizing

the volume pair. Deleting the target file system, however, clears only the file system's management
area. Resynchronizing the volume pair is not the same as performing an initial copy.

NOTE:

When the S-VOL is the file system managed by NAS Sync Image, unmount the

differential-data snapshots, and release the differential-data storage devices before using the

enas_fsdelete

command.

To resynchronize the XP Continuous Access Journal volume pair:

1.

At the secondary site, reserve the device file to be 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

, ...

2.

At the primary site, resume the XP Continuous Access Journal volume pair.

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

3.

At the primary site, verify that the XP Continuous Access Journal volume pair has been resumed.

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] => Resuming

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

Deleting XP Continuous Access Journal volume pairs

Completing XP Continuous Access Journal operations by deleting the XP Continuous Access Journal
volume pair in PSUS status differs depending upon whether you will continue using the file system
in the S-VOL or if you will destroy the file system.

When deleting the XP Continuous Access Journal volume pair in a status other than PSUS, you
cannot use that file system because the consistency of data in the S-VOL is not guaranteed.

To delete the XP Continuous Access Journal volume pair in PSUS status and continue using the
S-VOL file system:

1.

At the primary site, delete the XP Continuous Access Journal volume pair.

sudo pairsplit {-g group name|-d volume name} -S

2.

At the primary site, verify that the XP Continuous Access Journal volume pair has been deleted.

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