I have a couple development servers running centos 6.3 64bit that have
LSI 9211-8i SAS2 controllers connected to a SAS2 backplane. these
work fine with SATA hard disks (populated with a bunch of 3TB SATA
drives)...
I'm trying to install a OCZ Vertex3 SSD on each of the two servers to do
some ssd caching tests... system sees the drive, so I do the following...
# parted -a min /dev/sdu
parted> mklabel gpt
parted> mkpart primary ext4 2048s -1s
parted> q
# mkfs.ext4 /dev/sdu1
and it hangs at 'Discarding device blocks: 0/58607505' which I gather
is related to 'trim' aka 'discard'.
iostat shows this drive as 100% busy with no activity, and 1 pending
operation in the IO queue.

we're not running the /latest/ kernel, looks like its
2.6.32-220.17.1.el6.x86_64 so if thats significant, I can try an update.
for what its worth, the SSD"s seem to work fine plugged into a 9261-8i
sas2 megaraid on the same backplanes, but I want to do my caching tests
without the raid controller in the way.
anynone else seem issues like this with el6 and SSD on SAS ?

and exactly the same behavior with the latest kernel
2.6.32-279.9.1.el6.x86_64 and e2fsprogs-1.41.12-12.el6.x86_64

hmm, not sure thats this problem, as the drive seems to work fine as
long as I don't use "Discard' aka "SSD trim"...
I've just updated the SAS2 card bios and firmware to the latest, so lets
see what happens when I reboot... AHHHH, that fixed it :-/
for future reference...
9211_8i_Package_P14_IR_IT_Firmware_BIOS_for_MSDOS_ WindowsFirmwareHBA_9211_8i_IR2118ir.bin
and
9211_8i_Package_P14_IR_IT_Firmware_BIOS_for_MSDOS_ Windowssasbios_relmptsas2.rom
flashed using
Installer_P14_for_Linuxsas2flash_linux_i686_x86-64_relsas2flash
(the linux package3 doesn't include the firmware, so you need to
download the windows package too). the IR firmware supports raid while
the IT firmware is just a jbod HBA. my cards were already "IR" even
though I'm not using that feature, so I saw no reason to force the
restricted firmware on them.
ok, now I can move forward. this had be stymied for 24 hours... I've
not run into any problems where I had to update HBA firmware for years
and years and years.
