Hi!
I have StorageTek 2530 storage, which has two controllers. On host
side I have LSI LOGIC two SAS port cards. I've connected one cable
from LSI port1 to StorageTek ControllerA, and second SAS cable from
LSI port2 to StorageTek ControllerB.
OK. I've solved it - it seems that Linux host type in initiator
configuration is not turning on AVT on controllers. Instead, I had to
choose "Solaris (with Veritas DMP or other)", and now everything works!
Thank you, and hope this helps to others too.
I know that other people here will know more detail, but I think you have
another alternative which might be superior.
Instead of changing the initiator configuration to use AVT, you should
tune the device mapper to use RDAC.
To do that, I think you will need to adjust both the multipathd
configuration and recompile the scsi_dh_rdac kernel module after adding
support for "SUN"/"LCSM100_S".
Here's the RDAC multipath.conf I am using with a StorageTek 2510:
