Redhat, QLogic QLA2340 HBAs and EVA5000 and EVA8000 LUNs

Turlough McKeown — Wed, 30 Aug 2006 10:32:25 GMT

The following existing set up is linked to HP EVA SAN:
DL585 running Redhat 4 U4; kernel version 2.6.9-34.0.1
Two QLogic QLA2340 HBAs
Two EVA5000s, each presenting 4 LUNs each.

Adding EVA8000 to SAN, upgraded HP QLogic driver to 8.01.03p5-21

Two new LUNs presented from the EVA8000 are not listed by lssd. EVA8000 controllers are seen by hp_rescan -a. Details of lssd and config files below.

Are you sure your host designation/cigufartion on the EVA8000 is correct? Do the ports match the config on the EVA5000?

Not a zoning issue since.... well... you can "see' the EVA8k

I'm not sure if HP has fixed 'lssd', but I've found it quite buggy and not very reliable. I ended up changing the following line in 'lssd' from;

LETT_LIST=" a b c d e f g h i j k l m n o p q r s t u v w x y z aa ab ac ad ae af ag ah ai aj ak al am an ao ap aq ar as at au av aw ax ay az ba bb bc bd be bf bg bh bi bj bk bl bm bn bo bp bq br bs bt bu bv bw bx by bz ca cb cc cd ce cf cg ch ci cj ck cl cm cn co cp cq cr cs ct cu cv cw cx cy cz da db dc dd de df dg dh di dj dk dl dm dn do dp dq dr ds dt du dv dw dx "

to;

LETT_LIST=`ls /dev/sd* | sed -e 's/\/dev\/sd//' -e 's/[1-9]$//' | uniq`

This fixed most of the problems where 'lssd' didn't always show everything.

That being said, I would double-check to verify that the Qlogic HBAs see the new luns;

cat /proc/scsi/qla2xxx/* (note: it might not be qla2xxx for your HBAs, but it will be something like it).

If you see it at this level, then check /proc/scsi/scsi.

Presentation and Zoneing issue. Resolved. Thanks all.
