hi all,

i wonder anyone out there has seen this one:

env: adsm v2.1.6 running on aix4.1.5, ibm 3995 magneto-optical library

one of my mo disk has a read error on it and then when adsm tries to
access it, the following error occurs:




08/24/98 08:17:53 ANR8434I CHECKOUT LIBVOLUME: Operation for volume MBS04
                           in library MO-LIBRARY started as process 9.
08/24/98 08:17:53 ANR8300E I/O error on library MO-LIBRARY (OP=00006C03,
                          CC=314, KEY=05, ASC=3B, ASCQ=0E, Description=The
                          source slot or drive was empty in an attempt to
                          move a volume).
                          Refer to Appendix B in the 'Messages' manual for
                          recommended action.
08/24/98 08:17:53 ANR8437E CHECKOUT LIBVOLUME for volume MBS04 in library
                          MO-LIBRARY failed.




but when issure a "q libvol" this volume shows up in the library. did adsm
lose track of something or the library go wrong? by the way i tried to
update the access mode of the volume to read/write but it wouldn't work. i
then changed it to unavailable so that my archive request would go for
other volumes in the same pool (mbs05). looks like a ghost volume to me.
anyone has an idea where i can go from here?



thanks a lot!
