Hi
Normally we present disk via EMC DMX to our HP hosts and occassionaly via IBM SVC & DS8300.
When using the latter we normally only present a few LUN's ie no more than 8 as they are normally just a few large LUN's but I had occasion to present 16 smaller LUN's the other day.
We configure the SVC using scripts and can see all the LUN's being created correctly. When I look for them using ioscan I only see 8. On the DMX the next 8 would have the next controller number up and so on.
Out put from ioscan;

Now if I do a ioscan for LUNPATH I see all 16.

Also listing /dev/rdisk shows all the disks however only the first 8 are useable but you can interrogate them using scsimgr
root@hp90:# scsimgr get_attr -D /dev/rdisk/disk29 -a wwid
SCSI ATTRIBUTES FOR LUN : /dev/rdisk/disk29
name = wwid
current = 0x60050768018680d1a000000000004e4d
default =
saved =
I know this is probably a setting on the DS8300 or within the SVC scripting or possibly a license issue but does anyone have any information that can assist me with this?
Here is the config file the script uses, the first 4 fields are dates and names, the 5th is HBA number, 6th is a LUN ID, and 7th is LUN size.
