Re: Load source on old 9406-720

Thank you. This will be extremely helpful, I just need to find some good
'6713' drives.

Well you can install another drive, format it if it shows DPHnnnn (write
protected), then use the copy disk unit data - not the copy load source.

Now you can power down, swap the LS and the new drive and come back up.

You will however have this issue: The new LS drive is not RAID protected
because the O/S copied it's DATA not it's SECTORS. So a better option
would be:

Install it
Format. This is a good idea even if you don't need to.
Include it in RAID. If you formatted it first this will be very fast. If
not it will format it.
NOW copy disk unit data.
Power down
Swap the drives physically.
Power back up. Possibly you'll be able to exclude that drive from RAID
and if you can then you can physically pull it out. If you cannot
exclude it (because it has RAID strip data on it) then it will have to
stay for now.

If you attempt an 'out of the box' drive duplication it will fail to IPL
because the LIC absolutely cares about serial numbers. Every drive has a
copy of the list of drives in the ASP so it knows if they have all
checked in.

Not all is lost. And, I need some help understanding how these disks are

First, the 'failed' load source drive. For the time being, it's not

failed.

There were two bad blocks on the device, and I was lucky enough to have

a

good copy of the drive before it failed. I used the 'sg_reassign'

command

(part of a Linux SCSI package) to reassign the two bad blocks. Then, I
copied the good blocks back on the drive. Put the drive back in, and it
IPLs.

So, I poke around in DST. There is 1 ASP with seven drives. For some
reason, I thought there were two ASPs (one with 2 drives and the other

with

5). The entire thing is 95% full.

Now, I consider getting a spare drive and making it a copy of the first
drive. The big question: if I replace the drive and it's contents are
identical, is it going to care? Or will it fail because the new drive's
serial number isn't the same?

Or, is there a way to add the blank drive to the system and move the

load

source to it, then make it the new load source device?

When I got home this afternoon, tried to IPL the system and get a SRC
27419000. It turns out the other half of what used to be the load

source

mirror is now bad. The drive in the first slot has an unrecoverable

read

error, and the one in the second slot has a recoverable read error. (I
determined this by attempting to read them using SCSI tools on the PC).

Perhaps I should have left it at the scrap metal place.

There is a record for each DST user ID that contains a list of

that the user is allowed access to. I may be able to make the

'22222222'

user's entry have the function I need. I found some interesting areas

on

the disk during lunch, an audit log and the list of DST user profiles:
'SecServiceUserProfile' and 'SecPrivilegeList'. Interesting stuff.

What both of you mean, is. There is usually no way to derive the
password from whatever the OS stores, in linux's case its a shadow
file aka mathematical hash of the password.
I would just pop a lic cd and install, but it is technically a breach
of the os licence. And i believe it's next to impossible to buy a key
for such an old system.

Best regards,

PD: you are better off buying a 520 off ebay with the os key, i have
one, no client access and the such, but it does work.

Instead of using "22222222", try using "QSECOFR" as the DST userID.

I think I am going to have to write some tools to hack around with

an image

grabbing two

the

either the

That was,

if I remember correctly, a V3 something machine.

Your chances of finding the DST password are about the same as

that

of a

snowball inside a blast furnace, not gonna happen.

Use Larry's suggestion and from the console, signed on as

QSECOFR,

issue

the
CHGDSTPWD *DEFAULT command.

From there, take the serial number and just take each

To aid in your hacking, stop all parity protection (one less

abstraction

layer).

And good luck i doubt the users/pass are stored in plaintext.
You could also dump an op21 and look at the lic code part...

Keep us posted, i'm curious about this.

It's possible that it's the 2nd disk from the left.

Now on this quest to find the DST Password with a disk

I believe they are encrypted, and worse in EBCDIC so

noodling

for

recognizable stuff will be hard.

Why don't you run CHGDSTPWD and reset the QSECOFR DST

that

way?
