How much fun can you have with a simple thing like powerpath?
Here's the story: I have a (remote) system with access to a couple
of EMC LUNs. Originally, I set it up with mpxio and created a simple
zpool containing the two LUNs.
It's now been reconfigured to use powerpath instead of mpxio.
My problem is that I can't import the pool. I get:
pool: ######
id: ###################
state: FAULTED
status: One or more devices are missing from the system.
action: The pool cannot be imported. Attach the missing
devices and try again.
see: http://www.sun.com/msg/ZFS-8000-3C
config:
disk00 UNAVAIL insufficient replicas
c3t50060xxxxxxxxxxCd1 ONLINE
c3t50060xxxxxxxxxxCd0 UNAVAIL cannot open
Now, it's working up to the point at which it's worked out that
the bits of the pool are in the right places. It just can't open
all the bits. Why is that?
I notice that it's using the underlying cXtXdX device names
rather than the virtual emcpower{0,1} names. However, rather
more worrying is that if I try to create a new pool, then it correctly
fails if I use the cXtXdX device (warning me that it contains
part of a pool) but if I go through the emcpower devices
then I don't get a warning.
(One other snippet - the cXtXdX device nodes look
slightly odd, in that some of them look like the traditional
SMI labelled nodes, while some are more in an EFI style
with a device node for the disk.)
Is there any way to fix this or are we going to have to
start over?
If we do start over, is powerpath going to behave itself
or might this sort of issue bite us again in the future?
Thanks for any help or suggestions from any
powerpath experts.
