3510's and Device Names

Hi,

I have two 3510's (same config on both) connected to two different systems, on one system the disk device names are displayed when running the 'format" command are:

2. c3t40d0 <SUN-StorEdge3510-327U cyl 21920 alt 2 hd 64 sec 255>

/pci@1d,700000/SUNW,qlc@1/fp@0,0/ssd@w216000c0ff882674,0

3. c3t40d1 <SUN-StorEdge3510-327U cyl 21920 alt 2 hd 64 sec 255>

/pci@1d,700000/SUNW,qlc@1/fp@0,0/ssd@w216000c0ff882674,1

An on the other system:

3. c3t256000C0FFC865B7d1 <SUN-StorEdge3510-411I cyl 6574 alt 2 hd 64

sec 255>

/pci@1d,700000/SUNW,qlc@1/fp@0,0/ssd@w256000c0ffc865b7,1

4. c3t256000C0FFC865B7d2 <SUN-StorEdge3510-411I cyl 6574 alt 2 hd 64

sec 255>

/pci@1d,700000/SUNW,qlc@1/fp@0,0/ssd@w256000c0ffc865b7,2

5. c3t256000C0FFC865B7d3 <SUN-StorEdge3510-411I cyl 6574 alt 2 hd 64

sec 255>

- Why is there a shortened version for the target number in one and the long name for the target in the other?

- In other words, why does one display "t4" and the other display "t256000C0FFC865B7" as the target number?

- Is this configurable?

One array is configured in loop mode and one is in fabric mode.Not configurable.You might also want to upgrade the fw on the first system as you've got two different revs there.

Then in this case, "c3t40d0" is configured for "Loop Only" and "c3t256000C0FFC865B7d1" is "Fabric Point-to-Point"?By configurable, I mean is it possible to change the one in Point-to-point to loop only in order to get the shortened target name?

Yes. You should be able to configure both arrays to loop and get the shorter names. (You'll need to run devfsadm -C to clean up dangling links more then likely.)

Or course if one array is on a SAN then you can't really put it into loop mode and get shorter names. You could do loop mode and then TL mode on the switch but that doesn't get you much. In most cases using p2p when connected to a SAN is a good thing.
