Sir,
I am Sreenivasa Prasad V. working as systems Engineer for
DIGITAL Equipment , Bangalore - India.
I am working on a systems software called Media Robot
Utility. I need this product to be supported on Linux. I need your help in
getting the equivalent commands in Linux for Unix commands which we use in
our product.
The procedure is as follows.
All my questions below are started with an Asterisk (*) and are
underlined.
My product uses CLC (CAM Layered Component) Driver which comes
along with DIGITAL Unix . (I am working with Digital Unix).
*) Does Linux has built-in CLC(Cam Layered Component) Driver or I
need to Install this seperately ? If so from where can I get this driver ?
Is this freely available on the web ? If so please give the location.
My product is a back up product which mainly interacts with the
hardware devices. So we connect differenet hardware devices (what we call as
libraries )which moves the cartridges from slot to drive , drive to slots
and etc.
First of all we give command
# scu scan edt
Scanning all available buses, please be patient...
Which scans the system for all the devices connected.
Then we issue the following command to see all the devices connected
to the system.
opidc1 #scu show edt
CAM Equipment Device Table (EDT) Information:
Device: RZ28 Bus: 0, Target: 0, Lun: 0, Type: Direct
Access
Device: RZ26 Bus: 0, Target: 3, Lun: 0, Type: Direct
Access
Device: RRD42 Bus: 0, Target: 4, Lun: 0, Type: Read-Only
Direct Access
Device: RZ28L-AA Bus: 1, Target: 1, Lun: 0, Type: Direct
Access
Device: RZ28M Bus: 1, Target: 2, Lun: 0, Type: Direct
Access
Device: RZ29L-AS Bus: 1, Target: 3, Lun: 0, Type: Direct
Access
Device: TL891 Bus: 1, Target: 4, Lun: 0, Type: Media Changer
*) What is the equivalent commands in Linux for the above two
operations ?
This command shows the media changer with which we are going to work
with.
Depending on Bus, Target, LUN to which the device is connected we
create the device file using MAKEDEV.MC (This is a separate command in Unix
to create device files for media changers).
*) What is the equivalent command in Linux for creating the media
changer files (Just like MAKEDEV.MC command in Unix ?
In our case we use
setld -l <subset name > command to install our
product and use
setld -d <subset name > to uninstall the product.
*) What are the equivalent commands for the above two commands in
case of
Linux ?
Advanced Thanks and Regards,
V.Sreenivasa Prasad.
