If when you want to remove a XSB from a domain you get the message that the OS disks are being used by VxVM, and you know they’re not:
XSCF> deleteboard -c disconnect 09-0 XSB#09-0 will be unconfigured from domain immediately. Continue?[y|n] :y Start unconfiguring XSB from domain. Resource Information ------------------ ------------------------- /dev/dsk/c1t0d0s2 Device being used by VxVM /dev/dsk/c1t1d0s2 Device being used by VxVM XSB#09-0 could not be unconfigured from DomainID 2 due to operating system error.
The message “Device being used by VxVM” can be a bit misleading. They are not in use by VxVM, they’re in use by VxDMP!!!!
To remove this dependency you need to remove them from dmp by doing something like:
vxdisk -o alldgs list | egrep '^c0|^c1' | awk '{ print $1 }' | while read d;do vxdmpadm -f disable path=$d; done
After this you can remove the XSB using “deleteboard -c disconnect” without the “device being used by vxvm” error message
