Load balancing on FC HBA
We have many storage virtual disks presented via 2 SAN switches to a RP4400 running HP-UX 11.11 and using 2 FC HBA (each HBA connected to a different SAN switch)
Because of performance issues, we installed in the server 2 new FC HBA, so we have in total 4 new FC HBA (2 HBA connected to the same switch.
The question is how to implement load balancing on the four FC HBA to increase performance, and this for:
- Volume Groups contaning lvols using one PVG with strict allocation policy
- Volume Groups without PVG and strict allocation policy

Re: Load balancing on FC HBA
You could install software that allows for more verbose load balancing - SecurePath is the HP product. We're an EMC storage shop, so we use PowerPath for load balancing.
When you get to 11.31 it seems that SecurePath is part of the kernel - but that is for another thread.
Just a thought,
Rita

Re: Load balancing on FC HBA
With out it your only option is to manually round robin the pv-links/alternate paths.
On my older systems without any secure path I stagger the primaries over all 4 paths.
e.g.
dev1 on path1
dev2 on path2
dev3 on path3
dev4 on path4
dev5 on path1
dev6 on path2
etc..
If you wish to be more effective then monitor the io usage of each of your lvols and balance that way and review on a weekly/monthly basis. Something is better than nothing.
