[PATCH] ibmvscsi: Add 16 byte CDB support
------- Comment on attachment From brking.com 2009-05-28 10:12 EDT-------
Adds support for 16 byte CDBs to the ibmvscsi driver.
The issue appears fixed. I'll run the rest of our tests on this LUN to see if anything else falls out. sdb : very big device. try to use READ CAPACITY(16). SCSI device sdb: 20504608768 512-byte hdwr sectors (10498360 MB) Proposing for an exception as this can cause other problems, like pyparted exceptions when the 10TB disk as a proper GPT label, but the kernel can't see all 10TB of the disk. ------- Comment From brking.com 2009-05-29 15:48 EDT------- Patch submitted upstream: http://www.spinics.net/lists/linux-scsi/msg36361.html ------- Comment From brking.com 2009-06-12 14:10 EDT------- Patch accepted upstream: http://git.kernel.org/gitweb.cgi?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=fbc56f0801f58041a4372a030933bac076b46aad This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release.
