Hi all,

I can not present a new Lun with my EVA 5000 storage and Securepath ...

I have already 16 Lun's presented to the same server (Solaris 8), but can not add the 17th :-(

Do you know if we have a limitation with Solaris or Securepath ? (Config file to update, software limits ...)

Thanks a lot,

Fabien

i think it's the limit in the /kernel/drv/sd.conf file.... never tried that with secure-path, but i know that problem with MPxIO.. solaris just look for 16 (0-15) luns on a path per default, just add new entries in that file:

name="sd" class="scsi"
target=14 lun=0;

name="sd" class="scsi"
target=15 lun=0;
###
# new for a test
###
name="sd" class="scsi"
target=16 lun=0;

name="sd" class="scsi"
target=17 lun=0;

#
##EOF##

you will have to reboot to activate the new configuration for the sd kernel module.

hmmm.... there was also another thing about the sd.conf file and the lun depth... are you talking about more lun depth like c0t0d0 c0t0d1 c0t0d2 or really new targets like c0t0 c0t1 c0t2? ... if you are talking about the lun depth i think you have to edit the file that way:

find your controller, on my example it's controller 4 (c4t0d*) and add the following:

name="sd" class="scsi"
target=4 lun=0;
name="sd" class="scsi"
target=4 lun=1;
name="sd" class="scsi"
target=4 lun=2;

and so on....

i also can remember now a way to do that without rebooting that should work:

Thanks ...

Its related with Lun depth (C8t0d0 to C8t0d15).

I have to look in parallel if securepath is managing more than 16 Luns ...

I'll try your solution on a test server 1st :-)
