Hi there, We're having issues with our Adaptec RAID controller and I was wondering if anyone would be able to advise on how to go about resolving them. :)
The system: RHEL 5.1 x86_64 Kernel 2.6.18-53.1.4.el5 aacraid 1.1-5[2437]-mh4 (The default module shipped with the RHEL kernel) The controller: Adaptec 3405 + BBU BIOS : 5.2-0 (12415) Firmware : 5.2-0 (12415) Driver : 1.1-5 (2437) Boot Flash : 5.2-0 (12415) The disks: 4x Seagate ST373455SS (Firmware 0002) in a RAID10 The issue: We continually get what seem to be adapter lockups with the error: aacraid: Host adapter abort request (3,0,0,0) aacraid: Host adapter reset request. SCSI hang ? The controller hangs for a while, recovers, and everything continues normally. We've tried a replacement controller and a replacement set of disks (we swapped out all 4 disks) to no avail. The problem seems (?) to happen during spikes of IO -- like when the PostgreSQL autovacuum daemon kicks in. But not always. >From searching around LKML and Google, this seems to be a fairly common issue, but I'm not quite clear on the cause (hardware? software? firmware?) or the resolution. Any help would be greatly appreciated. Thanks!
