Cannot setup failover on LSI/Engenio array

I checked the SYSLOG and it seems it's trying to failover but not
successful.

Hi all,

I'm using a O200 IRIX host with QLogic 2342 HBA for a failover setup on
a Engenio 5884 (TP9500). In the Engenio knowledge base it mentioned a
step:

2. Enable the IRIX AVT feature if it is not enabled.

Automatic Volume Transfer.... How does one do that? Is there a special
failover driver provided by Engenio?

Any suggestion?

Regards,
Ernest
