I have 6 zfs pools and after rebooting init 6 the vpath device path names have
changed for some unknown reason. But I can''t detach, remove and
reattach to the new device names....ANY HELP! please

Is it even solaris? Just i wild guess: If the disk devices are in a directory (file system?) called "/pseudo", zpool won''t find them there, as it will only look in /dev/dsk by default. You could try "zpool import -d /pseudo" to have it look there instead. /ragge
Can you find the devices in /dev/rdsk? I see there is a path in /pseudo at least, but the zpool import command only looks in /dev. One thing you can try is doing this: # mkdir /tmpdev # ln -s /pseudo/vpathdd at 1:1 /tmpdev/vpath1a And then see if ''zpool import -d /tmpdev'' finds the pool.

Also, the zpool.cache may be out of date. To clear its entries, zpool export poas43m01 and ignore any errors. Then zpool import and see if the pool is shown as importable, perhaps with new device names. If not, then try the zpool import -d option that Mark described. -- richard On May 29, 2010, at 4:53 PM, morris hooten wrote:> I have 6 zfs pools and after rebooting init 6 the vpath device path names have changed for some unknown reason.

Are the indicated devices actually under /pseudo or are they really under /devices/pseudo ? Also, have you tried a ''devfsadm -C'' to re-configure the /dev links? this might allow you to recognize the new vpath devices... -Erik On 5/29/2010 4:53 PM, morris hooten wrote:> I have 6 zfs pools and after rebooting init 6 the vpath device path names have changed for some unknown reason.
