kernel alternate

UniRock — Thu, 19 Jun 2008 13:42:22 GMT

Hi Everybody,

During booting of rx2600/11.23 I gave /stand/hpux_test/vmunix kernel for booting, it booted very well.
Now the problem is evrytime I boot my server it get booted from that same kernel and not default one (/stand/vmunix).
How should I change this.

# kconfig -w
The currently running configuration was booted from 'hpux_test'.

Thanks.

Have you tried to boot server from /stand/vmunix after intrupting the ISL in next reboot?

No, i have not tried that...i thought that it would take the default kernel.
Changes at "HPUX>" prompt are permanent or only for that boot?

Hi,

Check for the boot string used in the AUTO file.

# efi_cp -d /dev/rdsk/c2t0d0s1 -u /efi/hpux/auto .
[rx2600]/
# more auto
boot vmunix

Above disk is the disk server booted from.
Am i looking into the right thing?

That's because /stand/vmunix reflects the current configuration (which means when you switch configurations by manually specifying in the boot string, it switched with you). [Think of /stand/vmunix more like a soft link to the current configuration's vmunix that can be reset at boot time].

kconfig will list your available configurations (I would have to assume you have something other than hpux_test here).

kconfig -n will boot the other configuration by default on the next boot.

Just booting to /stand/other/vmunix will do the same.
