zpool import -D should show any exported pools on the system and may be able to help show you what the state of the pool is in with devices. If not, then a fmdump -eV on the system may show what type of "device" the pool was, plus some other stuff about the pool.
e.g
pool = vault
pool_guid = 0x2bb202be54c462e
pool_context = 2
pool_failmode = wait
vdev_guid = 0xaa3f2fd35788620b
vdev_type = mirror
parent_guid = 0x2bb202be54c462e
parent_type = root
prev_state = 0x7
__ttl = 0x1
__tod = 0x4a27c183 0x9d8492d
Looks to me like the pool was just a stripe of two RAID5 devices on the EMC and you've lost at least one of devices, hence loss of the pool.

Hi all
I plan to install Solaris 10U6 on some SPARC server using ZFS as root pool, whereas I would like to keep the current setup done by VxVM:
- 2 internal disks: c0t0d0 and c0t1d0
- bootable root-volume (mirrored, both disks)
- 1 non-mirrored swap slice
- 1 non-mirrored slices for Live... (1 Reply)

I created a pool the other day. I created a 10 gig files just for a test, then deleted it.
I proceeded to create a few files systems. But for some reason the pool shows 10% full, but the files systems are both at 1%? Both files systems share the same pool.
When I ls -al the pool I just... (6 Replies)

I need to migrate an existing raidz pool to a new raidz pool with larger disks. I need the mount points and attributes to migrate as well. What is the best procedure to accomplish this. The current pool is 6x36GB disks 202GB capacity and I am migrating to 5x 72GB disks 340GB capacity. (2 Replies)

Other than export/import, is there a cleaner way to rename a pool without unmounting de FS?
Something like, say "zpool rename a b"?
Thanks. (2 Replies)

installed Solaris 11 Express on my server machine a while ago. I created a Z2 RAID over five HDDs and created a few ZFS filesystems on it.

ippool
IPPOOL(8) System Manager's Manual IPPOOL(8)
NAME
ippool - user interface to the IPFilter pools
SYNOPSIS
ippool -a [-dnv] [-m <name>] [-o <role>] -i <ipaddr>[/<netmask>]
ippool -A [-dnv] [-m <name>] [-o <role>] [-S <seed>] [-t <type>]
ippool -f <file> [-dnuv]
ippool -F [-dv] [-o <role>] [-t <type>]
ippool -l [-dv] [-m <name>] [-t <type>]
ippool -r [-dnv] [-m <name>] [-o <role>] -i <ipaddr>[/<netmask>]
ippool -R [-dnv] [-m <name>] [-o <role>] [-t <type>]
ippool -s [-dtv] [-M <core>] [-N <namelist>]
DESCRIPTION
Ippool is used to manage information stored in the IP pools subsystem of IPFilter. Configuration file information may be parsed and loaded
into the kernel, currently configured pools removed or changed as well as inspected.
The command line options used are broken into two sections: the global options and the instance specific options.
GLOBAL OPTIONS
-d Toggle debugging of processing the configuration file.
-n This flag (no-change) prevents ippool from actually making any ioctl calls or doing anything which would alter the currently running
kernel.
-v Turn verbose mode on.
COMMAND OPTIONS
-a Add a new data node to an existing pool in the kernel.
-A Add a new (empty) pool to the kernel.
-f <file>
Read in IP pool configuration information from the file and load it into the kernel.
-F Flush loaded pools from the kernel.
-l Display a list of pools currently loaded into the kernel.
-r Remove an existing data node from a pool in the kernel.
-R Remove an existing pool from within the kernel.
-s Display IP pool statistical information.
OPTIONS
-i <ipaddr>[/<netmask>]
Sets the IP address for the operation being undertaken with an all-one's mask or, optionally, a specific netmask given in either the
dotted-quad notation or a single integer.
-m <name>
Sets the pool name for the current operation.
-M <core>
Specify an alternative path to /dev/kmem to retrieve statistical information from.
-N <namelist>
Specify an alternative path to lookup symbol name information from when retrieving statistical information.
-o <role>
Sets the role with which this pool is to be used. Currently only ipf, auth and count are accepted as arguments to this option.
-S <seed>
Sets the hashing seed to the number specified. Only for use with hash type pools.
-t <type>
Sets the type of pool being defined. Myst be one of tree, hash, group-map.
-u When parsing a configuration file, rather than load new pool data into the kernel, unload it.
