powerpath or extra hbas

without the powerpath software I see I have 8 paths

4 standby and 4 active

but 1 active only has (I/O

with powerpath will that give me 4 paths active?

can I get more active paths by adding in extra hba?

    if you have 4 paths to SPA and 4 paths to SPB, change policy to Round Robin for your LUNs and you will see 4 active and 4 passive per LUN. PowerPath/VE provides more intelligent load balancing /failover.

    Hi There,

    if you are upgrading to CX4 and will have PowerPath/VE installed,then you want to enable failovermode=4 which will enable ALUA AND is a pre-requisite for VAAI.

    if PowerPath/VE isnt installed on a CX4, then you have the options:

    1. RR = loadbalancing without a path auto restore

    2. Fixed = no loadbalancing but auto path restore

    PP/VE offer both.
