    @Yogesh Thanks for information.But in some cases we have to run #vxdisk scandisks because in some scanerio vxdctl enable did not detect disks so sequences should be..#
    echo |format

    #vxdisk list
    #vxdiskadm ( 4 For replacement the errror disk , 5 for adding the new disk)
    #devfsadm
    # vxdisk scandisks #vxdisk list
    #echo |format
    #vxdctl enable
    #vxdiskadm
    #vxdisk list
    # /etc/vx/bin/vxdisksetup -i c5t0d0
    #vxdisk list
    #vxdiskadm (5th option)
    #vxtask list
    vxdisk list

    @Sandeep, you are quite right. :-), I would also like to let you know that vxdisk scandisks is a combined combination of “devfsadm + vxdctl enable” so the choice is yours :-). Also in solaris10 the arch. is so intelligent that it scan the vxdevices merely by doing rereading of the vxconfigd deamon. But yes in solaris 8 as I already stated there is a well known bug which prevents disks to scan under VxVm. Whatever you do at last you need a reconfig reboot. (though I managed to get it done without reboot in solaris 8, but later on it start showing degraded performance and Orcale provided the solu. to do a reconfig reboot so flush up the old devices unused reference links.). Hope this helps.

    Hi Ramdev

    ,Very good ArtIcle ,have removed the VMDISK,diskgroup and device etc .the disks are came from Direct attach storage ( DAS ) , what is the procedure to remove the DAS from Solaris 8. pl

  8. Yogesh Raheja says:

    @Shekar, thanks. For DAS, you need to remove the disks from OS and then phyically remove the DAS from server. After that run devfsadm -Cv to clean the unused ref. links.

    Hi,
    I faced issue as i tried to replace failed disk is part of rootvol and it mirror. After selecting option 4 in vxdiskadm and once confirmed the disk by “yes”, server unexpected shutdown and it gone to maintenace mode. Why it happened? Later it was fixed.
