Hello all, I've encountered the following on a fairly recent Linux system (CentOS 7, kernel 3.10.0-123.8.1.el7.x86_64): I was trying to attach a Promise Vtrak M500P raid array to the host by an adaptec 29320-lpe card. The raid is configured to a single very large lun, over 10TiBs. (it is working fine with an other, LSI based host adapter (mptscsih module), with the same system - but i have to replace the card due to not enogh pci-e slots). First, I have noticed,that the stock aic79xx driver thrown a lot of error after the READ CAPACITY(16) and READ(16) instructions. The reported lun size was 2TiB only. After a quick search I found that this issue was considered here before, in these threads: http://marc.info/?l=linux-scsi&m=119278917517261&w=2 http://marc.info/?l=linux-scsi&m=124650197016896&w=4 I have applied teh patch that upped the max_cmd_len variable to 16 in the driver, recompiled, but know I'm facing some even more interesting errors. As you will see, the device is know detected with it's correct size, even the partition table was read, but after that the whole thing is messed up. I'm not a expreienced kernel or scsi guy, so I'm asking a hand for fixing this, of course if that's possible. [ 102.794817] sd 6:0:0:0: [sde] Very big device. Trying to use READ CAPACITY(16).
