LUNs 08, 18, 40, 50.....etc etc show up 0 bytes
Hi all,
In a XP 256 or a XP512 it the ports are mapped with LUNS ending with 0 or 8, ex:08, 50, 40, 48 etc etc..they show up as zero bytes on the host side...also these show up in all hosts on that particular port even though LUN security is applied. HP tells that this is a SCSI 2 limitation...is this true??
And if yes, is there anybody who has a workaround to fix this issue so that this device does not show up in multiple hosts...

Regarding "...And if yes, is there anybody who has a workaround to fix this issue so that this device does not show up in multiple hosts..."
Assign unique World Wide Names (* WWN *) to each host. To view the WWN use 'fcmsutil'.
ioscan -fnkC fc (* list /dev/td devices *)
fcmsutil /dev/td0
############################################
Regarding "...LUNS ending with 0 or 8 ... show up as zero bytes...".
Please attach you 'ioscan', I believe these are controllers and should have no size. Is there class 'ext_bus' or 'disk'?
Here are possible disk examples:
ioscan -fnkC disk...
OPEN-3 2.461 GB
OPEN-8 7.348 GB
OPEN-9 7.385 GB
OPEN-E 14.568 GB
OPEN-L 36.436 GB
OPEN-M 47.171 GB
#############################################
xpinfo utility.
You should be cross referencing ioscan with xpinfo. If you don't have xpinfo then call the response center and they'll provide it. Its a proprietary utility that's hard to get a hold of.
