The aacraid module only reports the logicals and none-DASD devices to the scsi layer. There is no direct communication to any DASD devices. I have toyed with exporting the components of the arrays, but to please the (Security, RAID & OEM) gohds I need to ensure that R/W requests are not honored. I will look into producing a patch to MarkH for this once the current set (about a dozen patches pending) has finished bubbling through his hands ... The current mechanism for exporting this component information is via the applications, there is an SRB passthrough command that is in our OEM variant of the driver used for such a purpose. The SRB passthrough was rejected by the community and is not in the kernels.org driver and will remain a legacy requirement by the OEMs. Sincerely -- Mark Salyzyn -----Original Message----- From: linux-raid-owner@xxxxxxxxxxxxxxx [mailto:linux-raid-owner@xxxxxxxxxxxxxxx] On Behalf Of Augustine Ortiz, Jr. Sent: Tuesday, August 31, 2004 5:11 PM To: linux-raid@xxxxxxxxxxxxxxx; linux-scsi@xxxxxxxxxxxxxxx Subject: RE: Getting HD Serial Numbers in RAID Usually, most hardware RAID stuff does give software. However since this one (AACRAID/PERC) is such a common controller, this manufacturer didn't include it. We do have some for other systems, but they are in Windows, and I can't seem to figure out how to get the serial numbers through that either. Interestingly, if you have the arrays broken, you can pull the serial numbers just fine. Some RAID cards (ie. DAC90 chipset) will report all the disks when the kernel module is loaded. I figured I could just sorta re-work that stuff and see if I could probe it. I am having some trouble with the AACRAID module though. It looks like it grabs the info, but I can't tell if it does it when the drives are actually RAIDed. Thank you for the info, I will see if I can get it via the SMART stuff. I will post if I have any luck. Thanks!
