Hi Guys,
Can someone advice, I have a rx2620 install with hpux 11.23 and mirror disk. I have setup mirror disk . But how can I test on the alt boot , will the alt boot disk path be shown on the efi boot shell or I have to configure it in order to let it show.

when lvlnboot -v is issue, it shows the two boot disk path 0/1/1/0.1.0 and 0/1/1/0.0.0

pri 0/1/1/0.1.0 and alt 0/1/1/0.0.0

Please advice steps how can that be done???

Thanks in advance

Regards
Vincent

If you followed the good procedure then you can test it with the alternate boot path shown in het HPUX startup screen in the EFI

Many ways to check it. Do lifls on both disks and compare outputs. Also, you can set setboot primary to mirrored disk and boot from it.
setboot -v

Also while booting, you can interrupt and boot from alternate disk. (If you don't see boot from alternate option, you can add it.)

Hi Vincent,

First verify the primary path and alternate path using setboot command,

#setboot

If it is correct , you can reboot the server and select "HP-UX HA alternate Boot " from the EFI boot option .

Once teh server is up , you can verify which disk/kernel you booted from ,
#grep -i "Boot device" /var/adm/syslog/syslog.log

this should give the H/W path of alternate disk.
