How to remove the volume
Hi I wanted to know what command can I use to perform a rescan in Solaris10 u4/u5 64 bit machine. I know once the disks are added we can perform a rescan using the following commands drvconfig-->disks--> cfgadm OR devfsadm But they will detect the disks and once the disks are remove the entries are still shown unless the disks are removed. So is there another command or a script that could help me find that disks were removed from my solaris machine.
