we asked IBM several times already for the contents of the /proc/scsi/scsi file so that the relevant storage arrays can be added to the automatic whitelist, at which point no manual option is needed. Can we *please* get that information ? Could the bug reporter please provide contents of /proc/scsi/scsi? Thanks. -ernie *** Bug 115345 has been marked as a duplicate of this bug. *** Requested data or patch respectively can be found in bug 115345, which is a duplicate of this bug. Date: Fri, 16 Apr 2004 20:21:52 +0200 From: Martin Peschke3 <MPESCHKE.com> To: Don Howard <dhoward> Cc: Glen Johnson <gjlynx.com>, David C Fosmire <fosmire.com> Subject: Re: Sparse LUN support for IBM ESS It is not necessary to list various 2105 models separately. I suggest to add just one entry for all 2105 models along this line: + {"IBM", "2105", "*", BLIST_SPARSELUN}, All these boxes show the same characteristics with regrad to a sparse 64 bit LUN address space. I have discussed this with a colleague in the Tucson lab, where that box comes from. Besides, there is an F10 model as well, to my knowledge. I first thought that the BLIST_LARGELUN and BLIST_FORCELUN flags would be needed in addition. But one is deprecated and the other should not be required since all 2105 models identify themselves as SCSI-3 devices.

[The 2.4.9 version is similar] Are the 2105x models listed in his patch different from the 2105 that your patch addresses? Have the two of you been in contact about this issue? From Glen's posts to the IT ticket, it would appear not. Any 2105 model has got a sparse LUN space. This should give enough reason for including this line: + {"IBM", "2105", "*", BLIST_SPARSELUN}, If this also applies to 2145, which I am not the right person to answer, then another line for this box should be added. Doug Ledford's patch adding SCSI whitelist entries for IBM 2105/2145 devices has just been committed to the RHEL3 U3 patch pool this evening (in kernel version 2.4.21-15.9.EL). Would really like to get confirmation from IBM that the patch which landed in the U3 kernel does indeed address the problem, as it's different from the patch which Glen submitted and indicated had received testing.
