Flash Archive with MPXIO

It was necessary to exchange one SPARC Enterprise M4000 Server running Solaris 10 Update 9 with a replacement server.  I thought, "no problem"

Ran "flar create -n ben06 -S /S7420/ben06-`date '+%m-%d-%y'`.flar" on the original server to create a flash archive on NAS storage.

Upon restoring the flar onto the replacement SPARC Enterprise M4000 Server, problems appeared:

Rebooting with command: boot
Boot device: disk  File and args:
SunOS Release 5.10 Version Generic_144488-17 64-bit
Copyright (c) 1983, 2011, Oracle and/or its affiliates. All rights reserved.
Hostname: ben06
The / file system (/dev/rdsk/c0t0d0s0) is being checked.

WARNING - Unable to repair the / filesystem. Run fsck

manually (fsck -F ufs /dev/rdsk/c0t0d0s0).

Aug 22 10:25:31 svc.startd[7]: svc:/system/filesystem/usr:default: Method "/lib/svc/method/fs-usr" failed with exit status 95.

Aug 22 10:25:31 svc.startd[7]: system/filesystem/usr:default failed fatally: transitioned to maintenance (see 'svcs -xv' for details)
Requesting System Maintenance Mode
(See /lib/svc/share/README for more information.)

 It got fairly ugly from there: 

  • When I tried to run the fsck command, above, it reported "No such device"
  • Although "mount" reported that / was mounted read/write, other commands, such as "vi", reported that everything was read-only
  • "format" reported that I didn't have any devices at all!!
Eventually I realized that there seems to be a bug with Flash Archives + MPXIO

After I installed with the flar, I rebooted into single user mode from alternate media (bootp or cdrom), mounted the internal drive, and modified some files, changing "no" to "yes":

/kernel/drv/fp.conf:mpxio-disable="yes";
/kernel/drv/iscsi.conf:mpxio-disable="yes";
/kernel/drv/mpt.conf:mpxio-disable="yes";
/kernel/drv/mpt.conf:disable-sata-mpxio="yes";
/kernel/drv/mpt_sas.conf:mpxio-disable="yes";

Then, after a "reboot -- -r", everything was fine.
