It looks like SGI use the same FC vendor and they already have a workaround for this issue. The following patch adds the IBM version of it.

* [SCSI] sd: pause in sd_spinup_disk for slow USB devicesAlan Stern2005-09-061-5/+19
| | | | | | | | | | | | | | | This patch adds a delay tailored for USB flash devices that are slow to initialize their firmware. The symptom is a repeated Unit Attention with ASC=0x28 (Not Ready to Ready transition). The patch will wait for up to 5 seconds for such devices to become ready. Normal devices won't send the repeated Unit Attention sense key and hence won't trigger the patch. This fixes a problem with James Roberts-Thomson's USB device, and I've seen several reports of other devices exhibiting the same symptoms -- presumably they will be helped as well.

* [SCSI] return success after retries in scsi_eh_turAlan Stern2005-09-061-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | The problem lies in the way the error handler uses TEST UNIT READY to tell whether error recovery has succeeded. The scsi_eh_tur function gives up after one round of retrying; after that it decides that more error recovery is needed. However TUR is liable to report sense data indicating a retry is needed when in fact error recovery has succeeded. A typical example might be SK=2, ASC=4, ASCQ=1 (Logical unit in process of becoming ready). The mere fact that we were able to get a sensible reply to the TUR should indicate that the device is working well enough to stop error recovery. I ran across a case back in January where this happened. A CD-ROM drive timed out the INQUIRY command, and a device reset fixed the blockage. But then the drive kept responding with 2/4/1 -- because it was spinning up I suppose -- until the error handler gave up and placed it offline. If the initial INQUIRY had received the 2/4/1 instead, everything would have worked okay. It doesn't seem reasonable for things to fail just because the error handler had started running.

* [SCSI] embryonic RAID classJames Bottomley2005-08-303-0/+258
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idea behind a RAID class is to provide a uniform interface to all RAID subsystems (both hardware and software) in the kernel. To do that, I've made this class a transport class that's entirely subsystem independent (although the matching routines have to match per subsystem, as you'll see looking at the code). I put it in the scsi subdirectory purely because I needed somewhere to play with it, but it's not a scsi specific module. I used a fusion raid card as the test bed for this; with that kind of card, this is the type of class output you get: jejb@titanic> ls -l /sys/class/raid_devices/20\:0\:0\:0/ total 0 lrwxrwxrwx 1 root root 0 Aug 16 17:21 component-0 -> ../../../devices/pci0000:80/0000:80:04.0/host20/target20:1:0/20:1:0:0/ lrwxrwxrwx 1 root root 0 Aug 16 17:21 component-1 -> ../../../devices/pci0000:80/0000:80:04.0/host20/target20:1:1/20:1:1:0/ lrwxrwxrwx 1 root root 0 Aug 16 17:21 device -> ../../../devices/pci0000:80/0000:80:04.0/host20/target20:0:0/20:0:0:0/ -r--r--r-- 1 root root 16384 Aug 16 17:21 level -r--r--r-- 1 root root 16384 Aug 16 17:21 resync -r--r--r-- 1 root root 16384 Aug 16 17:21 state So it's really simple: for a SCSI device representing a hardware raid, it shows the raid level, the array state, the resync % complete (if the state is resyncing) and the underlying components of the RAID (these are exposed in fusion on the virtual channel 1). As you can see, this type of information can be exported by almost anything, including software raid. The more difficult trick, of course, is going to be getting it to perform configuration type actions with writable attributes. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] sr.c: Fix getting wrong sizePete Zaitcev2005-08-282-23/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here's the problem. Try to do this on 2.6.12: - Kill udev and HAL - Insert a CD-ROM into a SCSI or USB CD-ROM drive - Run dd if=/dev/scd0 - cat /sys/block/sr0/size - Eject the CD, insert a different one - Run dd if=/dev/scd0 This is likely to do "access beyond the end of device", if you let it - cat /sys/block/sr0/size This shows the size of a previous CD, even though dd was supposed to revalidate the device. - Run dd if=/dev/scd0 The second run of dd works correctly! The bug was introduced in 2.5.31, when Al fixes the recursive opens in partitioning. Before, the code worked like this: - Block layer called cdrom_open directly - cdrom_open called sr_open - sr_open called check_disk_change - check_disk_change called sr_media_change - sr_media_change did cd->needs_disk_change=1 - before returning sr_open tested cd->needs_disk_change and called get_sector_size. In 2.6.12, the check_disk_change is called from cdrom_open only. Thus: - Block layer calls sr_bd_open - sr_bd_open calls cdrom_open - cdrom_open calls sr_open - sr_open tests cd->needs_disk_change, which wasn't set yet; returns - cdrom_open calls check_disk_change - check_disk_change calls sr_media_change - sr_media_change does cd->needs_disk_change=1, but nobody cares Acked by: Alexander Viro <aviro@redhat.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

* [SCSI] add global timeout to the scsi mid-layerJames Bottomley2005-08-082-2/+17
| | | | | | | | | | | | | | | | | | There are certain rogue devices (and the aic7xxx driver) that return BUSY or QUEUE_FULL forever. This code will apply a global timeout (of the total number of retries times the per command timer) to a given command. If it is exceeded, the command is completed regardless of its state. The patch also removes the unused field in the command: timeout and timeout_total. This solves the problem of detecting an endless loop in the mid-layer because of BUSY/QUEUE_FULL bouncing, but will not recover the device. In the aic7xxx case, the driver can be recovered by sending a bus reset, so possibly this should be tied into the error handler? Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
