setboot info

[Fern H2O]

Hello All,

What is the difference between HA Alternate Bootpath & Regular Alternate Boot Path??

setboot
Primary bootpath : 0/1/1/0.0x5000c50017295c91.0x0 (/dev/rdisk/disk6)
HA Alternate bootpath :
Alternate bootpath : 0/1/1/0.0x5000c500172961d5.0x0 (/dev/rdisk/disk7)

Should they be the same? If not, can you give me an example of when they would be different?

Thanks,

hi,

primary/alternate = system disk boot

Primary = first boot disk
Alternate = second disk from LVM mirror
HA Alternate = installation CD/DVD rom

example :

testsrv1:/>setboot -v
Primary bootpath : 0/1/1/0.1.0
HA Alternate bootpath :
Alternate bootpath : 0/1/1/0.0.0

testsrv1:/>ioscan -fnkC disk |more

Since you can have 3 mirrors, you can also have 3 pathes.


This is the order:

Path Order = PRIMARY -> HA ALTERNATE -> ALTERNATE -> BCH

The man page says that HA Alternate is for servers that support hardware partition only.

Hi,

HAA Boot Path is only for those server which support Npar. This is a new concept related to booting in New Npar servers only. Boot Path priority is like

Primary -> HAA -> Alternate

Whereas, normal PA-RISC server are having

Primary -> Alternate.
