Serial
Port Configuration
All typical RAID setup and configuration can be done using the
LCD/Keypad, a serial port connection is not required. Using a
null modem serial cable, connect RAIDION LTX COM1 (DE9) to a COM
port on the PC or Laptop, start Hyperterm and configure.
Setting
Com Port and Baud Rate: (Illustration from
RAIDION U2W (Ultra2 / LVD) class products, use 9600 on Gandiva)
Terminal Emulation: 9600 Baud, No Parity, 8 Data Bits, 1 Stop
Bit, Half Duplex (Full Duplex w/firmware 2t43), No Flow Control.
Setting

Use Up or Down Arrow keys to select Terminal (VT 100 Mode),
press Enter, Main Menu should pop up and look like this:

Save configuration. Click on File | Save | ... You can now
use Hyperterm to configure and maintain RAIDION array.
Operation:
When both serial port and terminal emulation are configured,
press Escape key to 'wake up' serial port. A menu should
be presented with the same structure in terminal mode as that
with LCD/Keypad operation.

RAIDION
LTX Controller PCB Power and SCSI ID
J13 is attached to the SCSI
ID switch on the front of the module.
W8 is attached to the 2 wire
header that attaches to the activity LED on the module
Note: The red
wire goes to the front pin, see the "+" on the drawing?
J8 has only two pins
connected, Red, N/C, Black, N/C
This may seem odd, but the Gandiva needs to be set to a SCSI ID
that does not conflict with the adapter it is connected to.
Example, if you have a Corvette at SCSI ID 7, you CANNOT set the
Gandiva RAID module (bottom module) to the same SCSI ID of
7...Hilarity ensues... My SWAG is the four SCSI channels are
internal to the LTX, and are NOT considered when choosing a SCSI
ID for the LTX...
I wonder if this will do PUN/LUNs, something I have never
worried about with only SCSI devices on the chain, never SCSI
controllers in their own right...

Orientation of
Hard Drive SCSI ID Header
At first I was a bit mystified, but Micropolis used only four
wires instead of six.
Rotate the six position header so that the side with one wire is
to the bottom, for it is a common ground. The colored wire on
the SCSI ID header is the common ground. For the 0662, the
colored wire is on the right as you look at the drive from the
front.

Gandiva Codesets

How do I find out what version I am currently using?
Use LCD/Keypad, press Cancel key a few times to bring display
back to top of menu if not already there. Gandiva version level
will be located next to the RAIDUTIL label.
Gandiva Multimedia
Codeset
2M43.exe Gandiva Multimedia Codeset
Multimedia
caching scheme
Use with host applications which issue Read/Write
requests of sizes 64KB or larger to the Gandiva. The advantage
is even greater if:
Attendant stripe size for Gandiva is large- 64 or
128 blocks.
Requests from host are predominantly sequential.
Queue depth for host requests to Gandiva is
small- preferably 1.
Only one host process is accessing Gandiva for
block I/O.
Still not sure,
then use 2T43.
Note: Not [every] any
Multimedia application will benefit from the Multimedia
codeset. Some Multimedia programs generate Reads and Writes of
modest sizes (64 blocks or less), which would find the
Transaction caching scheme more suitable for their purposes.
Gandiva Transaction Codeset
2T43.exe Gandiva Transaction Codeset
Transaction caching scheme
Generally, hosts which generate small- and medium-sized file
I/O, and frequent file-system updates (e.g., most network
servers and database systems) are likely to benefit from the
transaction codeset. The Gandiva request sizes are typically
in the 2KB-to-32KB range. Use of the Multimedia codeset in
such a scenario will only produce overheads in finding memory
resources to process the hosts requests, resulting in the host
perceiving lower data- transfer rates than expected, and
commands taking longer to complete.
Usually, multi-user and multi-process systems will find the
Gandiva's Transaction Codeset to be a better performer, as
they tend to generate random I/O and more frequent commands
(especially if the host adapter in the system is making use of
the SCSI command-tagging feature).
The stripe-size setting on the array, which is also a factor
in the overall performance, is usually small for on-line
transaction processing (OLTP) applications- the default of 8
blocks or 16 blocks.
The files are self extracting, they include instructions, ASPI
drivers for Adaptec Host Adapters and the DOS download utility
raidutil.exe (bootable DOS floppy method). Check the utilities
page for other download tools via Novell, Windows 95, and
Windows NT.
Gandiva Cache Memory
The RAIDION LTX (Gandiva) can accommodate one pair of standard
72 pins SIMM (parity 72-pin, 60 ns, 4, 8, 16, 32 or 64 MB) as
Cache Memory. Both pair must be of the same size
SIMM. This provides from 8MB to 128MB of total Cache
Memory.
My Gandiva came with a pair of "Lite On" 1036D SIMMs.
The most ideal Cache Memory size is 32MB. Larger Cache
Memory size does not improve performance any further.
Identify Cache Memory size: Serial port, System
Information section via Statistics > System
Information. You can't use the LCD/Keypad.
Battery Backup: The LTX (Gandiva) does not have and can not
use the battery backup SIMMs.
Access to SIMM sockets: The controller module must be removed
from its plastic housing for desk top towers.
On the Gandiva, the entire top cover must be removed to access
the SIMM. Cut the warranty seal is done at your own risk.
RAID configuration information is stored on the disk modules,
not on the SIMMs. So don't worry about loosing your RAID
configuration when changing the SIMMs. But as always,
you should backup your data before attempting any changes to
the RAID.
