This suggests that there is some kind of bug in the layered storage
software. ZFS doesn't do anything special to the underlying storage
device; it merely relies on a few ldi_*() routines. I would try running
the following dtrace script:
#!/usr/sbin/dtrace -s
vdev_disk_open:return,
zfs should work fine with disks under the control of solaris mpxio.
i don't know about any of the other multipathing solutions.
if you're trying to use a device that's controlled by another
multipathing solution, you might want to try specifying the full
path to the device, ex:
zpool
Eric,
Here is what the customer gets trying to create the pool using the
software alias: (I added all the ldi_open's to the script)
# zpool create -f extdisk vpath1c
# ./dtrace.script
dtrace: script './dtrace.script' matched 6 probes
CPU IDFUNCTION:NAME
0 7233
So it does look like something's messed up here. Before we pin this
down as a driver bug, we should double check that we are indeed opening
what we think we're opening, and try to track down why ldi_get_size is
failing. Try this:
#!/usr/sbin/dtrace -s
ldi_open_by_name:entry
{
Eric,
Here is the output:
# ./dtrace2.dtr
dtrace: script './dtrace2.dtr' matched 4 probes
CPU IDFUNCTION:NAME
0 17816 ldi_open_by_name:entry /dev/dsk/vpath1c
0 16197 ldi_get_otyp:return 0
0 15546

Does format show these drives to be available and containing a non-zero
size?

zfs depends on ldi_get_size(), which depends on the device being
accessed exporting one of the properties below. i guess the
the devices generated by IBMsdd and/or EMCpower/or don't
generate these properties.
