fbackup with failure
Hello experts,
i have search in the newsgroups my failure, but without a hit!
I do not understand well English and it can be therefore which I mean solution already surveyed.
I have a problem with an LTO HP Ultrium 230i.
The Device hang on a HPUX 10.20 Server, in a external Storage on the SE-Bus.
The device was exchange yesterday while the device before was defective.
The Attitudes was exactly as the device before(SCSI-ID)
A Textfile of the ioscan was in the Attachment.
I use fbackup for the backup and recovery, and before the exchange he was functionally.
But after the exchange, i cant't use fbackup:
fbackup(1004): session begins on Sat Apr 12 21:08:49 2003
fbackup(3038): output file /dev/rmt/1m is not a valid device file for backup
fbackup(3019): would you like to enter a new output file?
What's the problem?
an ioscan -fnkCtape:
ioscan -fnkCtape

-----------------------------------------------The ioscan lists the device-file.
Why i can't use these or one of the files(rmt/1m or c1t1d0BEST).
I try isnf -e to recreate new files, without success!
Before this misfire i could use fbackup with little files (example the /tmp - directory),
But as i try fbackup with great files, i became the failure:
fbackup(3024): writing volume 1 to the output file /dev/rmt/c1t1d0BEST
fbackup(3012): WRITE ERROR while writing checkpoint record, at media record 118528
fbackup(3102): attempting to make this volume salvagable
fbackup(3123): could not read the previous checkpoint record
fbackup(3105): writing 2 EOFs and rewinding the tape
-----------------------------------------------
I modified the file:
#fbackup_config
blocksperrecord 64
records 64
checkpointfreq 256
readerprocesses 2
maxretries 7
retrylimit 5000000
maxvoluses 200
filesperfsm 200
So i can use the Ultrium on the SE-BUS(approximately the shoe-shinning effect, buffer-underrun)!
has the new device again a failure?
thanks for help an kind regards

Re: fbackup with failure
These patches are indicated: PHSS_26881 and PHSS_27585
You may have a bad SCSI cable and not a bad device.
What does LOGTOOL say about this HW path: 8/16/5.1.0?
STM > TOOLS > UTILITY > RUN > LOGTOOL > FILE > VIEW > RAW SUMMARY.
Note the first and last dates of transactions and calculate the difference. If the difference is short, like 4 hours, then this is important to note. Now read down the report of hardware addresses and observe the integer numbers in parenthesis. Anything over 150 in this 4 hour period should be called into HP for replacement.
Also check /etc/rc.log, syslog.log and /var/adm/messages (* dmesg *).

Re: fbackup with failure
Michael,
thanks for the answer. I look
in the logfiles and yes, you have right:
in the RAW-File-Log i see that the stape on the Hw-Path 8/16/5.... makes over 240 errors.
The failure came really from cable!
great thanks for your help!!
best regards
roland
