I've just upgraded to 2.1.108 and 5.1.0-pre2, and the machine seems to
be running fine. The problem is in the tag_info options. I have two
aha2940UW, the first one with 3 disks, and the second with two. I want
the tagged queue depth to be 32 for all except the second disk of the
first card, which should be 24, so the options passed by lilo are
aic7xxx=verbose,pci_parity,tag_info:{{32,24,32},{32,32}}
However, here's what /proc/scsi/aic7xxx/0 says:
Adaptec AIC7xxx driver version: 5.1.0/3.2.4
Compile Options:
AIC7XXX_RESET_DELAY : 2
AIC7XXX_TAGGED_QUEUEING: Adapter Support Enabled
Check below to see which
devices use tagged queueing
AIC7XXX_PAGE_ENABLE : Enabled (This is no longer an option)
AIC7XXX_PROC_STATS : Disabled
Adapter Configuration:
SCSI Adapter: Adaptec AHA-294X Ultra SCSI host adapter
Ultra Wide Controller
Programmed I/O Base: 8000
Adaptec SCSI BIOS: Enabled
IRQ: 15
SCBs: Active 0, Max Active 57,
Allocated 60, HW 16, Page 255
Interrupts: 1908546
BIOS Control Word: 0x0034
Adapter Control Word: 0x005b
Extended Translation: Disabled
Disconnect Enable Flags: 0xffff
Ultra Enable Flags: 0xfffb
Tag Queue Enable Flags: 0x0006
Ordered Queue Tag Flags: 0x0006
Default Tag Queue Depth: 24
Tagged Queue By Device array for aic7xxx host instance 0:
{32,24,32,255,255,255,255,255,255,255,255,255,255,255,255,255}
Actual queue depth per device for aic7xxx host instance 0:
{1,24,32,1,1,1,1,1,1,1,1,1,1,1,1,1}
You see that the "Tagged Queue By Device array" matches the lilo
options, but the "Actual queue depth per device" is quite different!!
What does this mean?
The same happens with the second adapter:
Tagged Queue By Device array for aic7xxx host instance 1:
{32,32,255,255,255,255,255,255,255,255,255,255,255,255,255,255}
Actual queue depth per device for aic7xxx host instance 1:
{32,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1}
Any ideas?
Carlos
