Boot problem diagnostics

Edit online

A variety of factors can cause a system to be unable to boot.

Some of these factors are:
  • Hardware problems
  • Defective boot tapes or CD-ROMs
  • Improperly configured network boot servers
  • Damaged file systems
  • Errors in scripts such as /sbin/rc.boot

If the boot process halts with reference code 2702 and displays the message "INSUFFICIENT ENTITLED MEMORY" use the HMC to increase the amount of entitled memory available for that partition.
