My system crashed. Now when I bring it back up it starts to behave strangely, indicating several system files cannot be accessed. I can sign on, as MANAGER.SYS, but most of the accounts that used to be on the system cannot be found. When I do a LISTF of PUB.SYS, most of the files have a message associated with them that reads as follows.

I believe the system disk experienced some “difficulties” at some point, and I’m not sure what happened or if it’s repairable. Of course I have a SYSGEN tape. But never having had to use one, I need to know if it contains the SYS account files necessary for me to begin reconstruction and reloading of accounts.

Paul Courry replies:

Bad UFID is a bad Universal File IDentifier. In other words, your file system is corrupted. You can try running FSCHECK.MPEXL.TELESUP (run with extreme care, reading the FSCHECK manual first). But considering the extent of the damage you probably will not be able to recover everything.

John Clogg replies:

Files, groups, and accounts on private volume sets are still there, but you will need to recreate the system directory entries for those accounts and groups. If you have BULDACCT output, that will make the job easier. It’s always a good idea to run BULDACCT periodically and store the result for just this eventuality.
