File ID errors mean a reach for BULDACCT
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.Since you have missing accounts as well as the UFID problem, it seems your system directory is damaged. I think it’s a safe bet that your system volume set is clobbered. You need to do an INSTALL from your SLT. This will re-install your operating system and give you a brand new directory
You will also need to restore the contents of your system volume set. Make sure you use the KEEP option so you won’t lose any files created by the INSTALL. You might want to purge or rename COMMAND.PUB.SYS before the restore, so you get your SETCATALOG definitions restored along with the files.
Larry Barnes notes:
Your SYSGEN tape may or may not have the SYS account on it. It depends on how the tape was created. You can generate a SYSGEN tape and have it include certain accounts. I usually include sys and TELESUP on the tape.
