Hello Folks,
(I am afraid) we are using FreeBSD as the initial boot/hardware/disk configuration tool for our Standard Windows Server builds.
We have a bootable CD that identifies hardware, partitions disk zero, copies the install files over and commences the Windows installation process.
This is working fine on a large number of machines/scsi controllers, but the ServeRAID is causing some issues. I am attempting to use the 4.11-Release IPS driver on an IBM xSeries 342 with a ServeRAID 4Lx RAID controller. (Controller BIOS/Firmware 7.10.18 - Two 18GB drives in a mirrored formation)
Whilst we have successfully tested 5.3 with the IPS driver for this purpose we are getting some odd errors in 4.11 (At this time it is not possible to migrate to 5.3 for our purposes)
When copying a large number of files (the i386 folder) using cp from a mounted CD to a DOS formatted partition on ipsd0 we are getting the following errors: ---cut here--- devstat_end_transaction: HELP!! busy_count for ipsd0 is < 0 (-1)! panic: vwakeup: neg numoutput
syncing disks... ips0: WARNING: command timeout. Adapter is in toaster mode, resetting to known state devstat_end_transaction: HELP!! busy_count for ipsd0 is < 0 (-1)! ips0: resetting adapter, this may take up to 5 minutes ips0: syncing config ips0: ERROR: unable to get a command! can't sync cache! ips0: adapter clear failed ips0: AIEE! adapter reset failed, giving up and going home! Have a nice day. ---cut here---
I get the same panic on an IBM xSeries 346 with a ServeRAID-7k controller (Six 15K RPM 36GB drives, two as RAID1, four as RAID0). The panic occurs at random points while sysinstall is copying distributions. If I do a minimal install, that completes successfully, but then the same panic occurs while building a new kernel.
5.4-RC1 seems to work fine, but I'm in the same boat as you; my customer doesn't want to upgrade to RELENG_5 yet.
I'm going to look at backporting the -CURRENT ips driver to RELENG_4, I'll post patches (and a PR) if I'm successful.
