Description Jani Myyry 2007-04-05 11:36:29 UTC
Description of problem:

The current RHEL5 CCISS (HP Smart Array) driver does not recognize
arrays with capacities over 2TB which are supported by recent HP
SAS/SATA controllers and MSA60/70 enclosures. The upstream already
supports large arrays and the newest RHEL5 kernel seems to work with
the same patch(es). More info:

http://lkml.org/lkml/2006/9/11/245
http://lkml.org/lkml/2007/2/23/250

We are using the first patch with a P800 controller and MSA60
enclosure (750GB SATA drives). The second patch seems to fix problems
in some situations so it might be wise to include it as well.


Version-Release number of selected component (if applicable):

kernel-2.6.18-8.1.1.el5

cciss support for > 2TB is included in a driver update planned for 5.1. See BZ
222852.
