https://community.hpe.com/t5/operating-system-hp-ux/tape-devices-with-luns-greater-than-7/m-p/3850096#M274693 We have a fiber to scsi router with 9 devices attached to it.<BR /><BR />We have found the HP knowledge base entry KBRC00010719, which describes the hard coded OS limit of 7 as the maximum lun number used for scsi. It describes a system that is used for disk devices that automatically increments the target number when the lun id reaches 8, 16, 24, etc...<BR /><BR />Why wasn't this same technique applied to tape devices?<BR /><BR />Why have such a small limitation on LUNs in the first place, considering that most other *NIXs support 256 luns (yes I know that Linux used to require a configuration change to enable 128-255).<BR /><BR />How do I get around this limitation?

It is what it is --- and it's documented. You might put in a request for a change.<BR /><BR /> Thu, 24 Aug 2006 14:56:40 GMT https://community.hpe.com/t5/operating-system-hp-ux/tape-devices-with-luns-greater-than-7/m-p/3850097#M274694 A.
