I've just installed a Sun Fire V20z with Solaris 10 6/06 using JET and a
flash archive.  The system filesystems are svm mirrors.  Unfortunately, the
machine doesn't boot, but just gets into the GRUB editor.  If I try to
access menu.lst, I get

grub> cat /boot/grub/menu.lst
Error 24: Attempt to access block outside partition

I can successfully access other files in the root fs (like /etc/passwd),
just everything under /boot fails.

The root command in GRUB shows the correct value: (hd0,0,d).  If I manually
enter the kernel and module commands, I can successfully boot the machine.

The partitioning might be somewhat unusual:

Part      Tag    Flag     Cylinders        Size            Blocks

  7 unassigned    wm    8916 - 8920       39.22MB    (5/0/0)        80325

  9 unassigned    wm       0               0         (0/0/0)            0

I.e. s0 is a mirrored zpool, s1 is a dedicated dump device, s3 is svm
mirrored /, s4 is svm mirrored /var, s5 and s6 are to be used for a Live
Upgrade BE, and s7 is the metadb.

Initially, the boot-args and boot-device eeprom variables were wrong: I had

setprop boot-args

in /boot/solaris/bootenv.rc, which caused a warning during boot about a
syntax error in bootenv.rc.

boot-device was broken either (an artefact from JET, I suppose):

boot-device=boot-device: rootmirror data not available.

I've just removed boot-device and corrected bootpath from the original

bootpath=/pci@0,0/pci1022,7450@a/pci17c2,10@4/sd@0,0:d

to

bootpath=/pseudo/md@0:0,3,blk

as adviced here:

Unfortunately, the machine still doesn't boot automatically, and I'm
currently stuck how to further investigate this.

Any suggestions?
