First clear your cache, you won't see any disks because:
1) You are in a reduced CLI set
2) You have invalid cache
3) More than likely, your units are inoperative because they are in
write-protect mode to ensure your data is safe because of the cache
being invalid.
This happens when the controllers are powered down without being gracefully
shutdown. It is not sure if the data contained in the cache is valid or not,
so it won't write it to disk and it is waiting for user intervention.
So, to fix said situation, you have to type this command in exactly:
clear this invalid_cache nodestroy_unflushed_data
Then do a 'sho this' to see if your cache errors are gone, cache state
should be GOOD. If this is the case, then proceed.
I see you you only have one controller, if you had two, you would repeat the
command for the other one, except that you would replace 'this' with 'other'
Ok, then, do a 'show units full' to see if your drive units are in
write-protect mode, or data-safety, inoperative, etc.
To fix that, type in:
clear <unit> lost_data
This will take a bit, and then your raidsets, mirrorsets, etc. will begin
rebuilding. Repeat for all units that are in that state. This will take
awhile, but you will then be able to reboot your server and access the
disks.
Not a big deal, just a little scary to someone who has never encountered
this before.

Subject: Digital StorageWorks 300AA & HSZ40C
Hi,
My Alpha 2100A perfectly boot with FreeBSD 4.6,
my problem (previous mail) was: "Put the VGA PCI card in first PCI block"!
I've surf a while before founding how to configure RAID on the mylex
controller, but it's finaly done.
Now, I'm seeking informations about a Digital StorageWorks 300AA
hooked to a PCI card: KZPSA SCSI Controller.
Is this StorageWorks Arrays supported on FreeBSD ? Has anyone an
StorageWorks
working with his alpha server ? Can you see disks in SRM or you needs
to access it via a special driver ?
On the server, I can see the SCSI interface KZPSA as pkb, doing show FRU,
and show CONFIG, but no disks.
I've hook a serial terminal to the Digital StorageWorks 300AA, playing at
9600 bauds and get a prompt. Any command fail and suggest to do a "SHOW
THIS_CONTROLLER" so i give you the result:
HSZ40C>SHOW THIS_CONTROLLER
Controller:
HSZ40 ZG61200481 Firmware V34Z-0, Hardware A02
Not configured for dual-redundancy
SCSI address 7
Time: NOT SET
Host port:
SCSI target(s) (0), Preferred target(s) (0)
TRANSFER_RATE_REQUESTED = 10MHZ
Cache:
32 megabyte write cache, version 2
Cache is INVALID. Cache containing unflushed data
has been removed from this controller
Battery is FAILED
Unknown unflushed data in cache
CACHE_FLUSH_TIMER = DEFAULT (10 seconds)
CACHE_POLICY = A
NOCACHE_UPS
Host Functionality Mode = A
This controller has an invalid cache module
Invalid cache -- CLI command set reduced. Type SHOW THIS_CONTROLLER.
Please-
see user guide to determine corrective action

Thanks for your tips.
