Booting Issues in Solaris

3."Timeout waiting for ARP/RARP packet"?

At ok> type printenv and look for these parameters .
  boot-device           disk
  mfg-switch?           false
  diag-switch?          false

if you see "boot-device net " or true value for the other two parameter change it to the values above.

In case you wants to boot from network make sure your client is properly configured in boot server and network connections & configuration are proper.

4."The file just loaded does not appear to be executable."

Boot block on the hard disk is corrupted .Boot the system in single user mode with cdrom and reinstall boot block .

#installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/c0t3d0s0

5."bootblk: can't find the boot program"

boot block can not find the boot programe - ufsboot in Solaris .Either ufsboot is missing or corrupted . In such cases it can be restored from the cdrom after booting from cdrom & mounting the hard disk 

# cp /platform/`uname -i`/ufsboot /mnt/platform/`uname -i`

6."boot: cannot open kernel/unix"

Kernel directory or unix kernel file in this directory is not found .Probably deleted during fsck or deleted by mistake .Copy it from the cdrom or restore from the backup tape.

# cp /platform/`uname -i`/kernel/unix /mnt/platform/`uname -i`/kernel

7."Error reading ELF header."?

Kernel directory or unix kernel file in this directory is corrupted.Copy it from the cdrom or restore from the backup tape.

# cp /platform/`uname -i`/kernel/unix /mnt/platform/`uname -i`/kernel

8."Cannot open '/etc/path_to_inst'"

System can not find the /etc/path_to_install file .It might be missing or corrupted and needs to be rebuild.

To rebuild this file  boot the system with  -ar option :

ok>boot -ar

Press enter to select default values for the questions  asked during booting and select yes to rebuild /etc/path_to_install

The /etc/path_to_inst on your system does not exist or is empty. Do you want to rebuild this file [n]? y

system will continue booting after rebuilding the file.

9."Can't stat /dev/rdsk/c0t3d0s0"

When booted from cdrom  and done fsck the root partition comes out to be fine but on booting from root disk this error occurs. The device name for / is missing from /dev/dsk directory and to resolve the issue /dev & /devices directories has to be restored from root backup tapes .
