Hi jgt, I have done above as suggested so now I have the RAID5 system booted with an emergency boot cd...
But I am not sure how to proceed.
I have tried to fsck the root filesystem but there isn't a vfstab on the system so I get an error.
I have tried running an fsck (the VXFS version) on all the devices in /dev/rdsk but that just resulted in an error from most of them.
So I am now unsure what steps to take to troubleshoot the original issue?
I can recreate the vfstab to be the same as the vanilla install I did on a single disk from which I created the emergency cd. Would that help??

Does this help
I cannot run fsck or vi from UnixWare 7 emergency floppy set.

However, you may find that Microlite Edge, is easier to use, as its recovery process is all menu driven. While it is a commercial product, it does have a 60 day full feature trial.

Sadly not. When I run umountall I get "Invalid argument"
When I run "fsck -F vxfs /dev/rdsk/c0b0t0d0s1" I get
invalid super-block
UX:vxfs fsck: ERROR: cannot initialize aggregate file system check failure,aborting ..."

Microlite's response was "Unfortunately, not having a current BackupEDGE backup RecoverEDGE will be of no use to you. Being that you're in the position you're in with a system that cannot boot, my advice would be to contact a data restoration company"

Install Microlite Edge on the RAID0 system.
Create the recovery CD.
Boot from the recovery CD to confirm that it works.
Re-install the RAID5.
Boot from the recovery CD.
What if?
Assuming that the data that you want is not in the root file system, create a backup of the RAID0 system, boot from the recovery CD and restore the root and stand file systems to the RAID5 disks. Then you should be able to boot 7.1.4 from the RAID5 system, and add the mount points and mount the non-root file systems.

Hmmmm! May be worth a try. Thanks! I'll suggest it to client (who are now sick of me).
But not tonight ... Enough trouble for one day! Thanks again. I'll let you know if it works.

I have never had a problem creating an Edge Recovery CD. However, in the past I have only installed it on Openserver. I will try this evening to duplicate your problem. Failing that, it is a long weekend in the US, so there will be no one at Microlite till Tuesday.
It is possible that the HBA driver was copied into the kernel during installation, but the library was not saved, and is not available to Edge to create its kernel.

Issue is:
I'm in process of attempting to get Microlite RecoverEdge create a bootable recovery CD ISO.
It is a case of 3 steps forward and 2 steps backwards! Solve one error and then hit another! But I'm finally nearly there. Just one more issue to conquer.
Namely that as it is creating the ISO I get an error "Error Enabling Statics" (not statistics).

The Online Help says of this error "One of the libraries could not be found. Make sure the program whose library dependency caused the error can be excuted normally on the system. this could occur if a program's required libraries do not exist. To see what those libraries are run ldd(1) giving the violating file as an argument. This could also mean the required library was not in the environment variable 'LD LIBRARY PATH'or that it was not in /etc/ld.so.conf (see ldconfig(8)).
