Operating Systems Solaris System is stuck at the OK prompt Post 302749367 by bluridge on Friday 28th of December 2012 06:37:16 AM
Thanks for the help! I have thought about the boot block maybe not being installed on the second drive. I thought with mirroring the boot block would be on the second drive because after all the root drive has the boot block installed so this would be replicated over to the second mirrored disk. I did not want to make it worse by running the installboot command. Also with the error messages showing /etc/inittab truncated or corrupted...this does not sound like a boot block issue?

The last file executed before the system boots up is /etc/inittab so does that mean the boot block was successfully executed if I coem to the ok prompt?

I am stil not able to figure out why we are getting this error on the /etc/inittab execution. If you have any ideas please throw them out!

I am trying to locate a Solaris 8 boot cdrom and try to boot in single user mode and copy over the default /etc/inittab file and see if this helps.

NAME
ccd -- Concatenated disk driver SYNOPSIS
pseudo-device ccd [count] DESCRIPTION
The ccd driver provides the capability of combining one or more disks/partitions into one virtual disk. This document assumes that you're familiar with how to generate kernels, how to properly configure disks and pseudo-devices in a kernel con- figuration file, and how to partition disks. Note that the 'raw' partitions of the disks must not be combined. Each component partition should be offset at least one cylinder from the beginning of the component disk. This avoids potential conflicts between the component disk's disklabel and the ccd's disklabel. The kernel will only allow component partitions of type FS_CCD. But for now, it allows partition of all types since some port lacks support of an on- disk BSD disklabel. The partition of FS_UNUSED may be rejected because device driver of component disk will refuse it. In order to compile in support for the ccd, you must add a line similar to the following to your kernel configuration file: pseudo-device ccd 4 # concatenated disk devices The count argument is how many ccds memory is allocated for at boot time. In this example, no more than 4 ccds may be configured. A ccd may be either serially concatenated or interleaved. To serially concatenate the partitions, specify the interleave factor of 0. If a ccd is interleaved correctly, a ``striping'' effect is achieved, which can increase performance. Since the interleave factor is expressed in units of DEV_BSIZE, one must account for sector sizes other than DEV_BSIZE in order to calculate the correct interleave. The kernel will not allow an interleave factor less than the size of the largest component sector divided by DEV_BSIZE. Note that best performance is achieved if all component disks have the same geometry and size. Optimum striping cannot occur with different disk types. Also note that the total size of concatenated disk may vary depending on the interleave factor even if the exact same components are concate- nated. And an old on-disk disklabel may be read after interleave factor change. As a result, the disklabel may contain wrong partition geometry and will cause an error when doing I/O near the end of concatenated disk. There is a run-time utility that is used for configuring ccds. See ccdconfig(8) for more information. WARNINGS
If just one (or more) of the disks in a non-mirrored ccd fails, the entire file system will be lost. FILES
