Per latest kmod-hpsa-3.4.4_1_RH1-1.el6_5.x86_64 available, the driver version is one lower than module shipped in 2.6.32-504.el6.centos.plus kernel and changelog of kmod doesn't show anything relevant to your issue. filename: /lib/modules/2.6.32-431.20.3.el6.x86_64/extra/hpsa/hpsa.ko license: GPL version: 3.4.4-1-RH1 description: Driver for HP Smart Array Controller version 3.4.4-1-RH1 author: Hewlett-Packard Company srcversion: 4B558C7818157360E7C4D89 Based on the data extracted, I would say, * The issue you have encountered is not due to missing driver support. * Enabling scsi logging would be the next step to figure it out the reason why tape is not functioning in latest kernel. @list, please shoot if any other suggestions .
