■ As the Sybase database administrator, release the database from quiesce

mode using a script such as that shown in the example.

See “Script to release a Sybase ASE database from quiesce mode”

on page 89.

Back up the snapshot volume. If you need to remount the file system in the

volume to back it up, first run fsck on the volume. The following are sample

commands for checking and mounting a file system:

# fsck -F vxfs /dev/vx/rdsk/snapvoldg/snapvol

# mount -F vxfs /dev/vx/dsk/snapvoldg/snapvol mount_point

Note: On Linux, use the -t option, and on AIX, use the -V option, instead of

the -F option for both commands.

Back up the file system at this point using a command such as bpbackup in

Symantec NetBackup. After the backup is complete, use the following

command to unmount the file system.

# unmount mount_point

Repeat steps 2 through 5 each time that you need to back up the volume.

In some instances, such as recovering the contents of a corrupted volume, it may

be useful to resynchronize a volume from its snapshot volume (which is used as

a hot standby):

# vxsnap -g diskgroup restore volume source=snapvol \

destroy=yes|no

The destroy attribute specifies whether the plexes of the snapshot volume are

to be reattached to the original volume. For example, to resynchronize the volume

dbase_vol from its snapshot volume snap2_dbase_vol without removing the

snapshot volume:

# vxsnap -g dbasedg restore dbase_vol \

source=snap2_dbase_vol destroy=no

Note: You must shut down the database and unmount the file system that is

configured on the original volume before attempting to resynchronize its contents

from a snapshot.
