My Sun StorageTek 2540 have redundant batteries, but a battery was failed.
After the battery failure, the server read/write performance was down (I assume)!
I read some doc from internet and I found a reason to performance down when storage array battery failed. A guy tell me you should change "Write Cache without Batteries" option to ENABLE on the storage volume using SSCS CLI utility.
Command is below:
/opt/SUNWstkcam/bin/sscs modify -a MyStorage -p disk_pool -b enable
I afraid that lost any data on the storage box after execute above command.
Please tell me what happening when I execute " /opt/SUNWstkcam/bin/sscs modify -a MyStorage -p disk_pool -b enable" command on the storage box?
BR,
Buyantugs

I have a Sun Sparc T2000 (Solaris 10 05-08) and have installed a PCI-X 4GB Single Port HBA card in it.
I have one StorageTek 2540 array that I would like to connect to the T2000.
For the moment it would be a single path connection, but I've ordered a 2nd HBA, so eventually it would be... (4 Replies)
We're moving our production 3510FC to development, so we need to replace the production 3510FC. The 6140 is nice, but pricey.
Here's the question: Would two 2540's (RAID 10) be 'faster' than one 3510? (RAID 10) and faster than one 6140 (RAID 10)?

Hi,
We have 12x1TB SATA disks in our array and I need to create 10TB volume. I defined new storage profile on array and when I tried to add volume, I faced with ~2TB limit for new volumes. I didn't find how to set another limit on my storage profile. Is there is a way to configure one large... (3 Replies)

Hi peeps,
Was wondering if anyone can help me, got a couple of storagetek 2540's that I need to configure. Trouble is I think they were brought as second user as all that came with them was cables.

Hi Guys and Gals,
Wionder if you could help me, got a problem with a controller on a storagetek 2540, dead when fully powered up but if you reboot, it is ok for a couple of seconds (and you can ping it). Then once the array is fully up, it goes faulty and is un-pingable.

Bought a Sun StorageTek 2540 SAN array a few years ago from a company that was going out of business. When we first set it up, we were able to get all the software (Common Array Manager) and firmware directly from Sun.
We just upgraded the drives, but the array is too large for the firmware. Now... (6 Replies)

acpibat
ACPIBAT(4) BSD Kernel Interfaces Manual ACPIBAT(4)NAME
acpibat -- ACPI Battery
SYNOPSIS
acpibat* at acpi?
DESCRIPTION
The acpibat driver supports ACPI batteries.
The battery status is made available through the envsys(4) API. The battery information can be displayed also with the envstat(8) command:
$ envstat -d acpibat0
Current CritMax WarnMax WarnMin CritMin Unit
present: ON
design voltage: 14.400 V
voltage: 16.267 V
design cap: 74.880 Wh
last full cap: 48.260 Wh
charge: 47.910 5.000% 0.414% Wh (99.27%)
charge rate: N/A
discharge rate: 16.641 W
charging: OFF
charge state: NORMAL
Depending on the battery, the unit of measurement is either watt-hour (Wh) or ampere-hour (Ah) for the capacity related information. From
these the ``charge'' is usually the most interesting value, but it is possible to derive useful information also from the other values. For
example, when acpiacad(4) is disconnected, the ``discharge rate'' gives a coarse approximation of the current power consumption. The ratio
between the design capacity and the last full capacity on the other hand reveals the overall ``health'' of deteriorating lithium-ion batter-
ies.
EVENTS
The acpibat driver is able to send events to powerd(8) daemon when a capacity state has been changed. The new state will be reported as the
fourth argument to the /etc/powerd/scripts/sensor_battery script. If a custom capacity limit was set via envstat(8), the acpibat driver will
report a user-capacity event to the same script when current capacity limit has been reached.
SEE ALSO acpi(4), envsys(4), envstat(8), powerd(8)HISTORY
The acpibat driver appeared in NetBSD 1.6.
BUGS
The ACPI specifications make a distinction between ``control method batteries'' and ``smart batteries''. The acpibat driver only supports
control method batteries. Furthermore, acpibat does not yet support some additional battery information introduced in the ACPI 4.0 standard.
