AIX

Hello Team,

In one of our machine which running in AIX 6.1 we doing the root mirroring. Currently the OS booted from the local disk and we have mirrored that in to the SAN disk. All went well and both are synced but when we making it as a multiboot its throwing the below error. Kindly advice.

Code:

bosboot -ad /dev/hdiskpower0
> 0301-154 bosboot: missing proto file:

> /usr/lib/boot/network/chrp.hdiskpower.proto

Hi,

is this EMC storage that you are using? If so, did you make sure you enable load balancing and failover functionality on the bootdevice by using the pprootdev tool which is provided by EMC? This tool enables bosboot to work correctly with the powerpath software. The information about the pprootdev tool can be found at the powerpath manual provided by EMC.

Hope this helps,

Vincent

Hello Vincent,

Hi,

did you try it in the following order as well?

Code:

pprootdev off
pprootdev fix

And after that:

Code:

pprootdev on

This usually fixes that problem.

Regards,

Vincent

We getting the below output.

Code:

#pprootdev off
hdisk0:Not part  of any powerpath device
#pprootdev fix
hdisk0:Not part  of any powerpath device
