I'm writing this report because I've exhausted my options with this issue and cannot find any viable solution. :( [1.] One line summary of the problem: Problem accessing Symbios-NCR 6285-3621 multilun device via Adaptec 2944W (aic7xxx) HBA. [2.] Full description of the problem/report: When configuring 2.6.16.13 kernel scsi subsystem with multilun support, I'm trying to access a Symbios 6285-3621 Array via an Adaptec 2944W HBA with aic7xxx module. All scsi "virtual devices" are recognized sdc-sdd-sde-sdf-sdg-sdh-sdi but then when the kernel tries to detect the partition tables it gets a lot of "Buffer I/O errors". The same hardware configuration was working on production as our database servers until last month with Solaris 7 and Informix IDS without any problem for at least 5 years, solid. We're now in the process of migration of this servers to Red Hat Enterprise Linux. The same issue was triggered with RHEL 4 AS stock up-to-date kernel (2.6.9-34EL).
