  1. Unable to mirror volume even though have loads of space


    We are trying to mirror a volume but get the following error:

    vxvm:vxassist:ERROR:cannot allocate space to mirror 436127744 block volume.

    the volume is 208GB and we have 208GB unused disks available. The output
    below is from vxprint -thf and show the volume we are trying to mirror:

    v data01 fsgen ENABLED ACTIVE 436127744 SELECT -
    pl data01-01 data01 ENABLED ACTIVE 436129024 CONCAT -
    RW
    sd oracled01-01 data01-01 oracled01 0 348105984 0 c3t4d0
    ENA
    sd oracled02-01 data01-01 oracled02 0 88023040 348105984 c3t4d1
    ENA

    I have noticed from this output that the plex size is more than the volume,
    could this be the cause of the problem?

    First you need to identify the volume length maximum in your syntax. Do this
    by running the 'vxprint -d' cammand.
    Disk group: yourdg

    TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0
    PUTIL0
    dm yourdg01 c25t14d3s2 - 86533920 - - -
    -
    dm yourdg02 c25t14d4s2 - 86533920 - - -
    -

    Tally up the length of the two disks. So 86533920x2=173067840. So your syntax
    would look like this:

    vxassist -g yourdg growby vol01 173067840 yourdg01 yourdg02

    Good Luck,
    JW
