Maybe... The L8i uses the same LSI chipset (1068E) but according to the OSol bug report it is only confirmed to exist up to svn126, so maybe 134 is unaffected? http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6894775 Normally array scrubs are fine for me too, I think what killed...

Yep... Sequential reads are actually faster now. Unsure if it was because of the change to max_pending or MSI settings though.

Looking through the OpenSolaris forums and bug report regarding this I've disabled MSI/MSIX and reduced min_pending and max_pending to 1. So far so good, it has even given a huge boost to multi-threaded read/writes.

Well I managed to provoke a response from my controller today while running two scrubs... Looks like it might have killed an array out of spite :( pool: online0 state: UNAVAIL status: One or more devices are faulted in response to IO failures. action: Make sure the affected devices are...

Controller is in IT mode and seems to detect the disks as though they were directly attached. I haven't tested with just the controller because I'm not really sure how to reproduce the problem, sometimes it might happen during heavy IO (e.g. multiple file copies) and sometimes it will happen...

I have a massive issue with my LSI 3081E-R (rebadged Intel) causing all sorts of weird errors. I still haven't been able to figure out the cause, but all IOPS to disks that are attached to that controller (via expander) will suddenly stop and often require the whole system to be hard rebooted...

I might give this a try with a slot cooler... I've done some more researching today and found that I'm not the only person having this issue and that others seem to think it is the controller itself. I bumped up the device timeouts in the controller BIOS but considering the issue is becoming...

The SAS expander is plugged into a PCIe x8 port on the motherboard (Intel S5500BC) and the power supply is a Seasonic X750, powering 20 drives in total. I don't think the PSU is the issue as it handles startup fine when it should be under the most load, and I intentionally went for a higher...

Hi all, Has anyone had an issue with the HP SAS expander where it seems to lock up or reset? I'm finding that all IO is halting and my console is being flooded with SCSI sense code errors and have observed that the drives then seem to go through a detection/power up cycle. After about a...
