OS boot failure and automatic reboot in a Sun T5220 SPARC server

  • 772

I have a strange boot issue on a Sun T5220 SPARC server with Solaris 10.

The last few changes I did on this server, for maintenance purposes were:

  • to delete some old directories (definitely not anything system-related, just some directories that I’m sure they are containing unused files) to free up some space
  • to install the library libiconv.1.14 for Solaris10 SPARC64
  • to install the patch 153074-01, to patch a known SSH-related vulnerability. Unfortunately, I forgot to boot in single-user mode before installing it.

Then, I rebooted the server from ILOM (I logged on in the console by start /SP/console and issued reboot). In the console, all I can see are the following lines printed again and again:

Boot device: /pci@0/pci@0/pci@2/scsi@0/disk@0,0:a  File and args: kernel/sparcv9/unix
SunOS Release 5.10 Version Generic_150400-59 64-bit

Hostname: unknown
The / file system (/dev/rdsk/c1t0d0s0) is being checked.

so, the server cannot boot the OS. How can I troubleshoot this situation?

    I haven't managed to find out the root cause of this problem. Nevertheless, a way to resolve it is to:

    1. Switch to the OK prompt.
    2. Boot in failsafe mode (ok: boot -F failsafe) and mount the root mount point on /a.
    3. cd /a/dev and del null
    4. Fix the broken OS files and symlinks (pkgchk -R /a -f SUNWcsd)
    5. Reboot
