Hi all, I moved from Sol 10 Update4 to update 6. Before doing this I exported both of my zpools, and replace the discs containing the ufs root on with two new discs (these discs did not have any zpool /zfs info and are raid mirrored in hardware) Once I had installed update6 I did a zpool import, but it only shows (and was able to) import one of the two pools. Looking at dmesg it appears as though I have lost one drive (although they are all physically accounted for). However both my pools are running raidz2 so even if I had lost one disc (another matter) I would still be able to expect to import them. If I swap back to my ufs root discs for update 4 then I can see the pool with import... I''m stuck as to what to do next? Anyone any ideas? -- This message posted from opensolaris.org

Anyone any ideas? >Look at the list of disks in the output of format(1M) in Update 4, compared with Update 6. Are there any disks missing? (It shouldn''t matter if the order is different.) If there is a disk missing, is it on a different type of controller from the others? (Just wondering if a disk driver might have stopped working for some reason between the two releases.) -- Andrew
Looking at format it is missing 12 discs! Which is probably not suprisingly the number of discs in the external storage controller. The other presnt disc have moved to c2 from c0. The driver is the same for both the discs (it is the HP CQPAry3 driver) and the external storage is on the same controller as the internal disc (but a different port) If I grep dmesg I see all discs appear to be found sd?? at cpqary30: target X lun 0 There are the correct number shown here. Ahhh... devfs... Ran devfsadm and it did the trick - it twigged when format couldn''t see the discs but they where found by the kernel!
