segunda-feira, 26 de dezembro de 2011

Using that feature you can clone on line your hp-ux system, clone your hp-ux guests (HPVM) and the target disk can be a SAN disk or a normal disk.

Follow a fast exaplanation to how to clone a system.

The fisrt step is test if your target disk is large enought for a DRD:


# /opt/drd/bin/drd clone –p –v –t /dev/dsk/cxtxdx

(if you are using 11iv3 you must use the disk name in this format: "/dev/disk/diskX")


Creating the Clone:

# /opt/drd/bin/drd clone -v -x overwrite=true -t /dev/dsk/c1t2d0
(if you are using 11iv3 you must use the disk name in this format: "/dev/disk/diskX")

-t = target disk

-v = verbose mode

-x = it's self explanatory..

log file:

/var/opt/drd/drd.log

Check the clone and original disk status

drd status command is executed to verify the clone disk and the original disk:

# /opt/drd/bin/drd status
