    Hello List,

    We have an HP SAN and when I present a lun from the SAN to one of the
    Solaris 8 systems I use the multipath utility spmgr to add the wwn of
    the disk and then devfsadm -C to get solaris to notice the disk. After
    that I can go into format and label and partition the new disk. All this
    is great but if I then want to remove that disk I again use spmgr to
    delete the wwn and devfsadm -C but afterwards when I run format, the
    disk is still listed even though it is no longer attached.

           6. c2t0d4 <COMPAQ-HSV110(C)COMPAQ-3000 cyl 31998 alt 2 hd 128 sec
    128>
              /swsp@0,1/sd@0,4
           7. c2t0d5 <drive not available: formatting>
              /swsp@0,1/sd@0,5
           8. c2t0d6 <drive not available: formatting>

    I thought cfgadm might resolve the problem but it doesn't seem to even
    know about the c2 controller. (See the cfgadm -al output below)

    Is there any way to tell Solaris that these devices are no longer
    present? The systems are an E250, E450 and a V880.

    Thanks,
    Vic Engle
