EVA5K VCS 3.028 (Active/Passive) - Can I perform Path Preferencing Online
Can I perform path preferencing online? I'd like to divvy up the VDISKS between the 2 controllers ..
And syntax in SSSU?

If I remember correctly, change the path referrence on the EVA might not produce the desired effect if there is active cache data on the current controller.
This is for HP-UX, right? In that case, "Path-[AB] - Failover/Failback" settings are not supported.
The supported way to cause static load distribution of vdisks across controllers is by setting the path preferrence with SPMGR. If necessary, it will tell the EVA to do a controller failover for a virtual disk.

You mean leave the PATH Preferencing on CV at "None" but do "spmgr select" on the host / SecurePath end - alternating between controllers?

- use "Path A/B - failover only" to distribute at the next boot of the EVA
- use SPMGR to force any changes now
