RE: chg-manual poor man's changer problems
(Warning: Stream-Of-Trace) OK, I'm getting closer. The reason that it keeps asking for a tape in the same slot is because it doesn't know what slot it's on. The message: - loaded Should really have a slot number in the , but doesn't. The variable $used in chg-manual is empty for unknown reasons. I wish I knew more shell script. OK, it looks like the line before the "loaded" message is the relevant one: used=`$MT $MTF $tape status 21 | tee -a $dbglog | $EGREP "$ONLINEREGEX"` This is placing the status message in the log, but it looks like no status message I've ever seen. My status messages look like this: [amanda@tape configdir]$ mt -f /dev/nst0 status SCSI 2 tape drive: File number=0, block number=1, partition=0. Tape block size 0 bytes. Density code 0x0 (default). Soft error count since last status=0 General status bits on (101): ONLINE IM_REP_EN I think that the grep is looking for 'ONLINE' and not finding it in your status message, so it doens't think the tape drive is ready, and asks you to insert a tape. Next steps would be to find out what AMANDA is invoking with $MT, and find out if you have an mt command like mine, and how to bring the two closer together. Sorry this took so long.

chg-manual poor man's changer problems
Dear Sirs. I already set up a HP SureStore 6x40i changer based tape device backing up our main server, now I tried to install on a secondary machine with a simple HP DAT drive a second piece of amanda, but without success. I followed the steps described in the really confusing manuals and other FAQ-based stuff. If I'm right, I have to setup the following in amanda.conf: (here are only the relevant entries) tpchanger "chg-manual" tapedev "/dev/nsa0" changerfile "/usr/local/perfector/amanda/services-backup/changer.conf" The entry "changerfile" should be set due the fact, that chg-manual driver script searches for several status-semaphores created with the name of the base changerfile. If I omit this, I receive an error. The targeted changerfile is either empty or I configure some parameters like slot /dev/nsa0 etc. But I receive allways the same result. After typing "amlabel -f CONFIG CONFIGLABEL slot [0-9] (I tried slot 0 to 9, but configured either slot 0 or 1, for testing purposes to see whether the result changes) I get the message that I'm to be to insert a cartridge into drive 0 or drive 1 (depends on what I configured or what slot I gave amlabel). I inserted already a cartridge, but I always get the same message after hitting RETURN. I checked /tmp/amanda/ amlabel.debug and there is a mt output I receive by 'mt status' - and this seems absolutely normal as it shows some informations about the used tape (DDS-2 and so on).

RE: chg-manual poor man's changer problems
Usually if AMANDA kicks out a tape during amcheck it is either because the tape isn't labeled or isn't the labeled tape she was expecting (for example, if you forgot to change the tape.) With no offense intended, have you already amlabel'ed the tape you are inserting during amcheck? Could you post everything that amcheck returns up (and including) the insert message? This might give a clue about why it is deciding to reject that tape and ask for another one. -Original Message- From: Hartmann, O.

When trying 'amcheck config' I get some infos about the holding disk and I was offered to insert a tape in slot 0 - and I should hit return. either I do immediately while the tape is already loaded into the HP DAT (4 GB DDS-2 drive) or I eject and reload it again, wait for the tape to be initialised and the hit return. Always with the same effect: I was offered to hit return again and load a tape into slot 0 - but nothing happened to the tape inserted into the tapedrive. When checking /tmp/amanda/changer.debug then I get a big file with this: Mode Density Blocksize bpi Compression Current: 0x24:DDS-2 variable 61000DCLZ -available modes- 0:0x24:DDS-2 variable 61000DCLZ 1:0x24:DDS-2 variable 61000DCLZ 2:0x24:DDS-2 variable 61000DCLZ 3:0x24:DDS-2 variable 61000DCLZ - Current Driver State: at rest. - File Number: 0 Record Number: 0Residual Count 0 - loaded - rewind /dev/nsa0 - status /dev/nsa0 Mode Density Blocksize bpi Compression Current: 0x24:DDS-2 variable 61000DCLZ -available modes- 0:0x24:DDS-2 variable 61000DCLZ 1:0x24:DDS-2 variable 61000DCLZ 2:0x24:DDS-2 variable 61000DCLZ 3:0x24:DDS-2 variable 61000DCLZ - Current Driver State: at rest. - File Number: 0 Record Number: 0Residual Count 0 - loaded - rewind /dev/nsa0 - status /dev/nsa0 Mode Density Blocksize bpi Compression Current: 0x24:DDS-2 variable 61000DCLZ -available modes- 0:0x24:DDS-2 variable 61000DCLZ 1:0x24:DDS-2 variable 61000DCLZ 2:0x24:DDS-2 variable 61000DCLZ 3:0x24:DDS-2 variable 61000DCLZ - Current Driver State: at rest. - File Number: 0 Record Number: 0Residual Count 0 - loaded -END- Well, it seems to be all right, tape is loaded, clear to be written on - but whats going on with the changer? It seems not to be willing to write anything :-( A normal tar, mt operations and so on work well with the tape and as user 'operator', so that is not a kind of a permission issue. :The config stuff looks OK to me, I would suggest leaving off the slot part :of the amlabel command. When I label tapes through chg-manual, I always just :`amlabel Config2 NextTapeName`, and if it asks me to put a tape in a :specific slot, I just re-insert the tape in the drive, wait for it to settle :down (it's an EXB-8505, they take a while) and hit enter. Solid as a rock. : :The only other thing that comes to mind is to make sure that the amanda user :has read and write permissions on the changerfile. : :Good Luck. : : :-Original Message- :From: Hartmann, O.
