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 ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] ZFS and IBM SDD Vpaths
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/vpat...@1:1 /tmpdev/vpath1a
And then see if 'zpool import -d /tmpdev' finds the pool.

Re: [zfs-discuss] ZFS and IBM SDD Vpaths
Also, the zpool.cache may be out of date.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.

Re: [zfs-discuss] ZFS and IBM SDD Vpaths
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...
