Can't log in with rsca / SCSI 1 to SCSI 2 adapter

[keyset6]

The system is a Siemens cave-man vintage 9006.3. The hard drive is likely the reason - the tech told me it's noisy (again). I replaced it a few years ago. When attempting to log on with rsca:

ROLMA1!login: rsca
Password:
Unable to change directory to "/usr/rsca"
login:

Even if I had the root password I probably couldn't get into Direct Amo with ufamos. I have hard drives on order. I'd really like to find and try a SCSI 1 to SCSI 2 adapter.We've got many old PCs that may have compatible hard drives if that adapter would work. Someone who just did a hard drive recovery on a 9006.6 Mod 80 received a replacement drive with the adapter I have in mind. Does anyone know a source for these adapters? It would be 50 pin SCSI 1 to (40?) pin SCSI 2.

Sounds like a hard disk issue. unix will continue to run even with a messed up drive as long as it doesn't need to use that area of the disk. When I build my unix/linux boxes I make multiple partitions for some purposes so that one accident like someone gaining access to my ftp server and uploading a bunch of crap won't take down the whole system, so it's possible /usr is its own partition and that's why you can still login.

I may have some information you seek but I'm not putting it here. Try to find me in the tek-tips linked-in group and message me. There have been changes over the years, and I don't know if I have the whole list.

Couldn't find you in groups, not sure if I was looking where I should. In front of me is another drive, instead of a 50 pin connector it's a 40, or actually a 39 since there's only 1 pin below the notch in the middle. To the right of that is are 4 pairs of pins with a jumper over the first pair to the far left, then the power connector which is the same as the 9006. To use that I'd need a 50 pin male to 40 pin female adapter, if such a thing exists.

So much for that drive, just spoke to someone that told me I was looking at an IDE drive, so I'll forget about that.

I was going to say - there are no 40-pin SCSI drives that I know of (I don't know everything) unless they are the new kind that plug into the front of a server. 40-pin in that configuration is typically IDE, with the jumper block being CS (cable select) and the Master/Slave configuration.

Aren't you the one I found a website where you could get an exact replacement for right around $100? If that was you, I don't know what you get paid, but you've probably blown more than that trying to jerry-rig something in place! ) I seem to recall someone else trying to do the same thing a while back.

You're more computer literate than I. Yes, you sent me a link for a replacement drive, thanks again for that. I saved the link as a reference if this other company we've been dealing with sends yet another bad drive or two.

Received 2 replacement hard drives from a vendor today. Tried one, it loaded whatever system's config and Unix that it came from ok. I replaced the hard drive in the system mentioned at the beginning of this thread with one I made from a backup a few weeks ago. By Friday I didn't even get a log in prompt. Had to do some changes since the backup I restored from was a few years old. I brought the Hard Drive/DAT assembly from the bad system back to my spare/test 9006. As expected the drive wouldn't load the system. I did get the recent DAT backup tape though. I'll attempt to restore the 'new' drive in my test 9006 with that tape to check a few other things I need to update.

Since I didn't know the rsca password on the new drive I received today I did a Unix Upgrade from the script. Had to go into Debug a few times for the script to continue. Got Unix restored from a tape I had. It has a couple utilities I haven't seen in years - Smartech TDS and EEA. What I wonder is could there be an easier way to reset the rsca password? Even if we knew which A1 file it resides in there's probably no way to manually delete that and load the default from the tape so it will prompt to set the rsca password.

You can login as root to reset the rsca password, but what the root password might be depends on how old the drive is, and when the last time was Siemens touched it.

I can use the root password on the drive that got installed on the running system which is how I reset that system's rsca password. The drive from the system it came from was a very old one that hadn't been on a service contract in years, in fact it doesn't even have Direct Amo as one of the menu choices so I usually just log in with root then go to Direct Amo.

At least I was able to restore the hard drive I just got from the vendor with the above systems backup from about a month ago. There's a couple other things I can now list which I wish I did previously before the drive totally failed, like DEST and some LDPLN entries. I set up my own version of DISA using an OPLSMA line into a Loopstart CO trunk. Over the ties I can get dial tone from that system again. This time I made note of the trunk and station ports if it ever needs to be reconfigured again.

Well it sounds like you're either in a good place now or getting back to one!
