AIX 4.3.3 / Failed hdisk3 / Replacement

To All,

I have a 7025-F50 that has a failed/failing SCSI drive. It is clicking and putting tons of disk errors into the logs. This is a stand-alone disk with archived data on it. It is listed as lv05 hdisk5. It has one volume group on it with one file system.

I could use some help on the proper way to remove the drive and any associated "stuff" with it so that I can replace it.

I figure I need to unmount the filesystem, delete the file system, delete the volume group and then do an remdev on hdisk3? Then pull the drive. Then replace the drive with a new one and add all of the above back in.

I cant get the filesystem to unmount. I get this error:

umount: 0506-349 Cannot unmount /dev/lv05: The requested resource is busy

Any and all help would be greatly appreciated!

Mark
