Hp Cciss Drivers

I've finally started to test the newer versions of RedHat 6. Install Printer Without Cd Epson. x and Scientific Linux on HP ProLiant hardware. My previous installs were in virtual hardware, so I didn't notice the raid controller driver change. The first thing I realized on a physical installation was that the drive array devices are now SCSI /dev/sdX names versus the longtime /dev/cciss/cXdX block devices.

Is there any performance impact? Is there any overlap in terms of the card supported? Download Emulator N Gage Untuk Hp E63. Has there been a similar change on the Windows side? HP has a good write-up of what the differences are here: (PDF) High points: • Puts devices in the standard /dev namespace, which you already noticed.

The cciss driver is a block driver as well as a SCSI driver and only the tape drives and medium changers are presented to the SCSI midlayer Furthermore, unlike more straightforward SCSI drivers, disk I/O continues through the block side during the SCSI error-recovery process Therefore, the cciss driver implements only the first two of these.

• Modernized interaction with the SCSI layer in newer kernels. • hpsa is a SCSI driver, cciss is a block-driver. • This will change device numbering, if that matters. • This is why the /dev namespace changes • The /sys controls for the driver will change. • Older cards (before the P400-era cards) still require CCISS • It may be the case that cciss and hpsa will both load if cards requiring them are present. The Windows side is untouched.
