vxvm root disk booting problem - solved with boot -a. How?
Hi All,
We had a Sun Netra T1 go down the other day, the root disk was mirrored using vxvm. Upon boot from either disk, we had the following error appear:
no problems i thought. I'm well aware of this issue with VX. However I discovered I couldn't boot from vx root or mirror (same errors), we tried the cd, and the that failed too (suspected broken cdrom).
having given up all hope, I randomly tried a 'boot -a' (accepting all defaults) which somehow got me into multiuser, but with no vxvm partitions installed, or vx processes running. From there we were able to recover the system.
Can anyone shed any light as to how or why 'boot -a' worked? Not being a VX guy, I'm really scratching my head, and can't recreate this problem.
Hi,
I have an openserver 5.0.0 machine in the office. The sysad of that machine left years ago without leaving the password to anyone.
I was wondering if someone has a copy of the boot / root diskettes (rescue) for this version? Or perhaps if anyone knows a download link / location in the... (0 Replies)

Hi,
Can you help me on booting x86 server configured under VxVM. Server boots fine normally from both the disks but if I try to boot server from mirror disk without starting veritas, then it does not boot.

Hi guys,
thanks for helping out.
If you have two boot disk mirrored and your primary boot disk fails, how will you boot the system from the second disk?
Thank you very much for your assistance on this matter.

installboot
installboot(1M)installboot(1M)NAME
installboot - install bootblocks in a disk partition
SYNOPSIS
installboot bootblk raw-disk-device
The boot(1M) program, ufsboot, is loaded from disk by the bootblock program which resides in the boot area of a disk partition.
The ufs boot objects are platform-dependent, and reside in the /usr/platform/platform-name/lib/fs/ufs directory. The platform name can be
found using the -i option of uname(1).
The installboot utility is a SPARC only program. It is not supported on the architecture. users should use installgrub(1M) instead.
bootblk The name of the bootblock code.
raw-disk-device The name of the disk device onto which the bootblock code is to be installed; it must be a character device which is read-
able and writable. Naming conventions for a SCSI or IPI drive are c?t?d?s? and c?d?s? for an IDE drive.
Example 1: Installing UFS Boot Block
To install a ufs boot block on slice 0 of target 0 on controller 1 of the platform where the command is being run, use:
example# installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk
/dev/rdsk/c1t0d0s0
/usr/platform/platform-name/lib/fs/ufs
directory where ufs boot objects reside.
/platform/platform-name/ufsboot
second level program to boot from a disk or CD

The installboot utility fails if the bootblk or openfirmware files do not exist or if the raw disk device is not a character device.
