Operating Systems Solaris Luxadm display not showing a LUN as expected

Sorry, i have no idea about veritas multipathing solutions.
I only used native multipath on every linux/unix i worked on.

But, if you presented everything and MPXIO is not enabled..
You will see multiple devices (number depending on number of paths configured) for one presented LUN in the format output.

Also, check achenle suggestion.

*Edit achenle on cards which support NPIV the code you wrote will catch also Max NPIV Ports: resulting in output which is faulty (but will do no damage just print ILLEGAL WWN or alike)

Best regards
Peasant.

Hi Diego,

Your version of Solaris supports 16364 LUNS (I think), but do you know if there are any restrictions on the HBA's firmware.

It might be worth adding an other LUN if possible to see if the problem is related to that broken LUN only or if it affects any new LUNS as well to check if you have reached some kind of limit - or if the problem lies elsewhere.

Looks like operating system sees the lun on all paths normally (as device files are created), but luxadm command does not display correctly.
Could this be a bug of some sort ?

Does veritas multipath software recognize it as the same lun ?

What are the device names under /dev/vx for both the working and non-working LUNs?

@Gull04
I don't think so, as the same number of LUN is in an OK state on the other node of this cluster.

@Peasant
Correct, path are OK on format, but not on luxadm. As stated, the same OS is on the other node of the cluster, and the LUN is ok.
Veritas recognize the different paths of the "broken" disk as different ones, and here is my true problem Smilie

@achenle
The names are ibm_ds8x002_6146 for the "broken" one and ibm_ds8x002_4900 for the "correct" one.

Is there any way to "force" the luxadm infos?

Thanks!

For the record, I resolved doing a
Code:
luxadm -e offline

on one of the not-aggregated paths, and than did a simple
Code:
cfgadm -c configure

and
Code:
devfsadm

.
