Our V480 w/ Solaris 9 would not boot properly. After recreating the LUNs on our StorEdge A1000, and then performing a reboot, the machine just keep cycling through the boot process. No error messages, it keeps trying to reboot over and over again.
Any ideas?
We managed to do a stop+a and get into the ok prompt. Once we got into ok prompt, we did a test-all to check if all devices are okay.
Next step is to try to boot to single user mode from ok prompt:
boot -s
or
boot cdrom -s (if we need to)
there is most likely a problem with the Storedge filesystems --- "non-existent" /etc/vfstab entries are being mounted ... boot the box from cdrom or from the network and fix your entries
Is there a need to boot from cdrom? I think that a single user mode boot will be just fine.
you're right ... except the box keeps cycling through the boot process until a stop-a kills the cycle ... would be a lot easier if the box behaves properly 
We finally figured it out. The cause of the problem was a bad pci video card. From our research, we found that this problem is usually caused by a bad RAM. We replaced all of it and we still had the problem.
thanx for everyone's reply.
What's a video card doing in a server anyway?!
we need the video card for the kvm switch.
