Hi ,

Some HP Integrity servers released after June, 2006 have support for native tape boot. Some systems available before that time received firmware updates that enable tape boot. However, not all systems will receive firmware updates to enable tape boot. Also, only some SCSI HBAs will be supported for tape boot. Fibre Channel and SAS HBAs do not support native tape boot.
For HP Integrity systems that do not support tape boot, or those that do with tape drives connected to HBAs that do not support tape boot, Ignite-UX will still continue to support tape recovery support via a method called Tape Recovery with No Tape Boot Support, Dual-Media Recovery, or Two-Step Media Recovery. This method requires that a tape drive be connected to the client, that you boot the client from the HP-UX installation media, and that you choose options to continue installation or recovery from tape.

Hi Himacs:

And if you want to know which servers under which conditions support a native tape boot, see:

Recovery Procedure

To recover a failed system disk or volume group, you would do the following:

1.Mount the System Recovery tape on the tape drive
2. Boot the system
3.Interrupt the boot sequence to redirect it to the tape drive
4.Indicate no interaction with ISL.
5.Allow the system to complete the process.
#

NOTE: If the recovery process encounters a configuration change/error, it goes into the interactive mode, and displays the Ignite-UX welcome screen with the following options:

[Install HP-UX ][ Run a Recovery Shell ] [ Advanced Options ][ boot] [Help]

At this point, select the Install HP-UX option. (You are installing from the customized media). Select Advanced Installation (recommended for disk and filesystem management) Change your configurations and continue. Selecting disks should be done with care, as any existing data on the disks will then be lost.

Hope it will resolve ur issue.

Meanwhile many Itanium servers support native tape boot, but IMHO this may be even slower than the 2-step method.
