  • 1.  Move disk from local machine to SAN

    HI,

    I have a rootvg mirrored. Among the two disks one disk is on SAN another disk is on local system.
    In this case how can I move the local disk to SAN without any downtime.
    Also the base OS is booting from local disk.

    Thanks for your idea.

    IS there any chance to do the same without unmirroring?

    for LV in $(lsvg -l rootvg | awk 'NR>2 {print $1}')
    do
    printf "$LV ... "
    migratepv -l $LV hdiskX hdiskY
    printf "\n"
    done ;
    bosboot -ad /dev/hdiskY
    bootlist -m normal -o hdiskY
    chpv -c hdiskX

    Where:
    extendvg includes a new hdiskY in rootvg
    hdiskX is the disk in original rootvg
    hdiskY is the new disk, or new LUN
    migratepv is the real command working the data/volume migration
    bosboot makes the new disk bootable (a disk containing a boot LV)
    bootlist makes IBM Power firmware aware of a new bootable disk
    chpv -c clears the boot section of old OS hdisk
