Re: San and devices

If it's an EMC array you may want to check that the SPC-2 bit is
enabled. Also, depending on how the array is set up you may see 4
devices for each physical LUN (redundant FAs on the array will present 2
devices on each of your HBA paths).

Subject: [rhn-users] San and devices

 

My 5.4 box has a single HBA card with 2 ports connected to my Storage. 2
Luns are assigned to my HBA card. Under /dev instead of seeing 4 devices
I can see 12 devices from sdb to sdm. I am using qlogic driver that is
bulitin to the OS. Has any one seen this kind of situation?
