This is a generic problem, not limited to ZFS. The
It turns out this was actually as simple as:
stmfadm create-lu -p guid=XXX..
I kept looking at modify-lu to change this and never thought to check the
create-lu options.
Thanks to Evaldas for the suggestion.

Hello again.
As I kind of explained earlier, and as your screenshots display, your actual
root filesystem dataset is named "rpool/ROOT/zfsBE_patched". However either the
boot loader (eeprom parameters on SPARC) or much more likely the "rpool"
ZFS-pool level attribute "bootfs" contains a differe
Hi Ketan,
What steps lead up to this problem?
I believe the boot failure messages below are related to a mismatch
between the pool version and the installed OS version.
If you're using the JumpStart installation method, then the root pool is
re-created each time, I believe. Does it also instal
So y my system is not coming up .. i jumpstarted the system again ... but it
panics like earlier .. so how should i recover it .. and get it up ?
System was booted from network into single user mode and then rpool imported
and following is the listing

The press embargo on Intel Z68 chipset has been lifted and so there's a bunch
of press on it. One feature called Smart Response Technology (SRT) will sound

The thing is- as far as I know the OS doesn't ask the disk to

Hello,
Trying to understand how to backup mirrored zfs boot pool 'rpool' to tape,
and restore it back if in case the disks are lost.
Backup would be done with an enterprise tool like tsm, legato etc.
As an example, here is the layout:
# zfs list
NAME USED AVAIL
I can't actually disable the STMF framework to do this but I can try renaming
things and dumping the properties from one device to another and see if it
works- it might actually do it. I will let you know.

Keep in mind zfs_vdev_max_pending. In the latest version of S10, this is set
to 10. ZFS will not issue more than the value of this variable requests at
a time for a LUN. Your disks may look relatively idle while ZFS
has a lot of data piled up inside just waiting to be read or written.

Sorry, I did not hit this type of error...
AFAIK the pool writes during zfs receive are done by current code (i.e. ZFSv22
for you) based on data read from the backup stream. So unless there are
corruptions on the pool which happened to be at the same time as you did your

You can try to workaround - no idea if this would really work -
0) Disable stmf and iscsi/* services
1) Create your volume's clone
2) Rename the original live volume dataset to some other name
3) Rename the clone to original dataset's name
4) Promote the clone

Technically "bootfs ID" is a string which names the root dataset, typically
"rpool/ROOT/solarisReleaseNameCode". This string can be passed to Solaris
kernel as a parameter manually or by bootloader, otherwise a default current
"bootfs" is read from the root pool's attributes (not dataset attribu
