I'm performing a storage migration between two fiber channel connected EMC arrays. I've already moved the data from the disks on the old array to the disks on the new array. Now I want to remove the old disks from the OS so the array can be un-zoned without the OS noticing and raising alerts because disks have disappeared. I really don't want to have to reboot to achieve this.
I can do this without issue with non-MPxIO disks, but for MPxIO disks my usual technique isn't working.
My usual technique is to use
luxadm -e offline /dev/rdsk/cXtXdXs2 devfsadm -Cvc disk
Here's an example. This is in my test lab which isn't connected to EMC arrays, but an old SENA (A5100), but it should work the same for any FC connected disks. As you can see it doesn't work at all
v480:root $ stmsboot -L | grep /dev/rdsk/c6t20000020371AC414d0 /dev/rdsk/c5t22d0 /dev/rdsk/c6t20000020371AC414d0 /dev/rdsk/c2t22d0 /dev/rdsk/c6t20000020371AC414d0 v480:root $ luxadm -e offline /dev/rdsk/c6t20000020371AC414d0s2 v480:root $ stmsboot -L | grep /dev/rdsk/c6t20000020371AC414d0 /dev/rdsk/c5t22d0 /dev/rdsk/c6t20000020371AC414d0 /dev/rdsk/c2t22d0 /dev/rdsk/c6t20000020371AC414d0
Trying to remove the underlying devices doesn't work either
v480:root $ luxadm -e offline /dev/rdsk/c5t22d0s2 Error: Invalid pathname (/dev/rdsk/c5t22d0s2) v480:root $ luxadm -e offline /dev/rdsk/c2t22d0s2 Error: Invalid pathname (/dev/rdsk/c2t22d0s2)
Does anyone know how this is done?
