Added more devices from the same frame - paths missing for one device

Question

This host already had 12 devices presented from this Clariion. We presented 10 more. Powermt looks right for all the devices except the last one added (not that I think that is the problem.) Pseudo name=emcpower15a CLARiiON ID=APM00041100xxx [Host X] Logical device ID=60060160AE701000C83377C8FCF3DB11 state=alive; policy=CLAROpt; priority=0; queued-IOs=0 Owner: default=SP B, current=SP B ============================================================================== ---------------- Host --------------- - Stor - -- I/O Path - -- Stats --- ### HW Path I/O Paths Interf.

All the connectivity on the frame is right or we'd have the same problem for all the devices, not just this one. I don't want to take the shotgun approach of tossing Solaris Scsi commands at it but I guess I can if no one knows why this is.

I wonder if their sd.conf configured to go far enough for target 43 and target 42. Can you get a copy of sd.conf and see if it looks something like this:

name="sd" parent="lpfc" target=43 lun=16 hba="lpfc0" ;
name="sd" parent="lpfc" target=42 lun=16 hba="lpfc0" ;

They're supposed to be using them.

dynamox · Answer

are you using sd.conf and lpfc.conf ?

I wonder if their sd.conf configured to go far enoughfor target 43 and target 42. I agree, this is the most likely cause based on symptoms.

dynamox · Answer

good ..so what does it look like now ?

TyfoidKid · Answer

That was it.She had this in her sd.confname='sd' parent='lpfc' target=42 lun=15;name='sd' parent='lpfc' target=43 lun=15;name='sd' parent='lpfc' target=47 lun=16;name='sd' parent='lpfc' target=48 lun=16;So you add device 16 you're going to have an issue.Thanks for the help.
