Full Discussion: POWER6 VIO Failover
Operating Systems AIX POWER6 VIO Failover Post 302319474 by filosophizer on Monday 25th of May 2009 10:31:27 AM

I have tried this with two new VIOs and it works fine.

I have loaded the SDDPCM & MPIO drivers then configured the SAN Storage for both VIO Servers.


However, I have an existing VIO Server which already has the SAN Storage and when I install the MPIO and SDDPCM drivers I get the following errors.

Anyone come across this ?

Also, lsdev -Cc disk should show something like
hdisk10 Available 04-01-02 IBM MPIO DS4700 Array Disk



1- My client partitions are OFF
2- SAN Storage DISKs are allocated to HOST_GROUP_VIO
3- HOST_GROUP_VIO has two VIO Servers: VIO_1 and VIO_2

VIO_2 = which is the scratch installation works fine... but the problem is with VIO_1
