LDOMS has gone

[Juergen Schroeder]

Hi,

after a powersupply error my ldom configuration has gone.

ldm list
NAME STATE FLAGS CONS VCPU MEMORY UTIL NORM UPTIME
primary active -n-cv- UART 8 16G 0.3% 0.0% 39m


The ldoms were on iscsi devices. The iscsi devices are restored.

I have the configuration commands for the ldoms. Can I rebuild the
configuration. Will the content of the ldoms will be remain?

Host has solaris 11 and the ldoms had solaris 10.

TIA

Did somebody forget to save the config to the SP ???? :-(

Yes.

I have done this a number of times.
Just rereun the commands/script and then boot.

Then save the config to the SP ! :-)

"have". The OS is still on the underlying disks
:-)

And take a look at the boot prom settings,
like auto-boot and boot-devices. Perhaps you
have to reconfigure them as well.

Did you manage to recover them?

Yes, since 3 hours the servers are back.

In the meantime some old bare metal servers does the Job. Problem was to get
the meantime data merged.

I had the create scripts for thee 7 ldoms on the 2 T5 servers.
Works like a charm, ok the second zpools have to be reimportet.

I testet the restart of the LDOMs and host some times only with reboot.
Never with powerdown ...
I found that a lot of people fall into this trap..

Shortest answer was

Yes, easily done. Hence why a poweroff should be performed as part of
system testing before it goes live :-)

Or RTFM :-)
