we are running Irix 6.5 on our octane/sgi computers - these computers come with an external Sony MOD drive attached via a scsi cable. We have backed info to 2.3 gig MOD disks over the years and woule like to duplicate the MOD's. I believe there are 3 ways to do this:
add a second drive to the SGI possibly using the instructions at Installation Guide SGI. System Administration. Adding a magneto-optical drive to the computer and make copies/clones of our current MOD disks. (I believe once we physically attach another MOD drive we will have to 'load' the drive(s) and enter some commands that copy the first MODs' disk and then transfer to the second MODs' disk. We would also want to verify the files made it to the new MOD disk a list of the files with details).
I also understand there are MOD disks duplicators that will do the job (minus the verification step?)
Copy all of the MOD's data to our harddrive, eject the original MOD, put in a new MOD and make a new copy to the MOD drive and verify.
We could use any/all help with the above and have limited IRIX skills -
All these three possibilities will work, but probably (and depending on the number of disks involved) the disk duplicator will be the one least costly, because it can work automatically.
You can verify a medium (any medium, including your MODs) by simply reading from it. Put the newly copied MOD in a drive, and use something similar to this script:

May i ask then, why you post in the experts forum? It surely can't be because of the nature of your problem, which is entry-level at best, yes?
I hope this helps.

After doing some searching i found no such thing as a media duplicator for MO-media, so perhaps such a thing isn't being produced.
You could build such a device (at least half-automated, that is) yourself by installing two MO-drives in one system. It doesn't even have to be a SGI-workstation, a simple Linux workstation would suffice, which would probably lower the price tremenduously.
Then start the following script (or some variant of it) as root. I have:
You can stop this script by pressing "CTRL-C", otherwise it will loop forever, asking for one disk after the other.
Got server that I want to have an 'image' of disk to keep in case of failure. What I want to be able to do is, in the event of disk failure, remove system disk replace with cloned disk (same slot) and reboot.
Trouble is I cant take this server down to single user.

I am trying to list the name of files on an MOD - I use the command

Hi all,
Can anybody help me with how I can connect a usb pendrive or external disk to a Sun Server which runs on Solaris 9? I am able to connect the usb drive to a windows server easily and copy files but am wondering if it is possible to do that with Solaris.
Any help will be appreciated. thanks. (3 Replies)
I have been tasked with archiving Oracle tables. The data is on raw devices, and possibly will span multiple logical volumes.
Has anyone ever had to do this? How did you accomplish it?
Any references to accomplish this would be greatly appreciated.
