I have a AIX server running VSP disks now. We are EMC users before.
So we dumped Powerpath and now we are using native AIX MPIO. We have Hitachi support for MPIO installed. Our disks are ok, mapped for our two HBA's like bellow:
Enabled hdisk400 fscsi2
Enabled hdisk401 fscsi2
Enabled hdisk402 fscsi2
Enabled hdisk403 fscsi2
Enabled hdisk400 fscsi1
Enabled hdisk401 fscsi1
Enabled hdisk402 fscsi1
Enabled hdisk403 fscsi1
FAILOVER ok, but LOAD BALANCE appears to be not configured. See "iostat":
ssaturno:/>iostat -a |grep fcs
fcs1 6071.4 259.1 387802311 132862434
fcs2 0.0 0.0 0 0
All traffic goes over FCS1 and FCS2 remains free.
What i need to change to our disk traffic go to FCS2 also?
Thanks for any answer.
