V490 sol8 no disks found

Hi,

I have 2 V490, both with sol8 installed from DVDROM.

both have 2 SCSI disks installed

I run format and get the list of disks

machine1:

Searchingfor disks...done

Doing restore testing

ufsdump to tape

ufsrestore from tape to other machine.

boot sequence stops at /etc/rc2.d/S01MOUNTFSYS

on the mountall command

unable to mount , get prompted for root password for system maintenance

Hostname: fake-name1

metainit: fake-name1: there are no existing databases

The / file system (/dev/rdsk/c1t1d0s0) is being checked.

Can't stat /dev/rdsk/c1t1d0s0

/dev/rdsk/c1t1d0s0: CAN'T CHECK FILE SYSTEM.

/dev/rdsk/c1t1d0s0: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.

WARNING - Unable to repair the / filesystem. Run fsck

manually (fsck -F ufs /dev/rdsk/c1t1d0s0). Exit the shell when

done tocontinue the boot process.

at this stage when i run a format I get no disks found.

I have removed the metadevice entries from/etc/system

I have change the devices in/etc/vfstabback to native disks c1t1d0s0 etc

same prob

I have deleted /dev/ and /device and recreated by restoring from backup for the correct machine.

same problem

What have I missed?

How can I do a bare metal restore of a system if it is not back to the original hardware?

I have also deleted/dev and/devices then added a/reconfigure in the boot disk ANDboot disk1 -r

but it just hangs the machine just after the copyright message

so I restore the correct /dev and /devices andboot disk1 -ragain

get back to the mountall problem, give root password for system maintenance.

give the root password

format searches for a long time ( 30 seconds )

no disks found!

I hope it is something simple I have missed

Thanks in advanced

Peter

I have also tried running devfsadm

get this error

devfsadm: mkdir failed for /dev 0x1ed: Read-only file system

devfsadm: open failed for /dev/.devfsadm_dev.lock: Read-only file system

same for disk command

drvconfig also complains about read-only filesystem during unlinking

umount to remount /

bash-2.03# mount -o remount /

mount: /dev/dsk/c1t1d0s0 no such device

Thanks

Peter

With the v480/490 you need to remember that the targets are on c1 NOT c0.

This has caused an issue for many people and their jumpstart installations and meta configs.

There was also a patch that corrected the instance number from c0 to c1.

Prior to the patch, the DVD ROM was NOT detected setting the targets to c0. Applying the patch and doing a reconfig reboot would cause the mount of the root volume to fail, because the /etc/vfstab or md.tab was pointing to c0 and the root disk is now at c1.

This is where the /etc/path_to_inst would come into play.

the easier why to fix the path_to_inst is to rundevfsadm -p /a/etc/path_to_inst -r /aprovided your mounted disk is on /adone in single user mode from CDROM
