Subject: Reducing SCSI timeouts?
Hi everybody,
due to faulty tape drives, we have "lost" some of our LTO4 tape volumes, i.e.
these volumes are no longer readable by any of our other tape drives. AUDIT
VOLUME sometimes stalls at the first file to check and throws errors and gets
reduced to a crawl.
The only way out for us is currently "DELETE VOLUME DISCARDD=YES", but for
obvious reasons, I do a "MOVE DATA" beforehand to rescue the data that any of
the drives is able to read. (No copy pools were yet configured)
Since we have "a couple of" volumes to check, I'd like to get some insight if
it is possible to reduce the SCSI timeout value for the tape drives, since we
have to wait ~15 minutes for a single "CANCEL PROCESS"
I tried:
echo "180" > /sys/class/lin_tape/IBMtapeX/device/timeout
But that didn't work out. Any hints?
* TSM for Linux/x86_64 - Version 6, Release 2, Level 3.100
* RedHat 5
* lin_taped 1.68.0-1
Thanks in advance!
BR,
Sascha

Hi, Sascha. I don't know how to reduce the timeout, but IPLing the drives
should allow the process to cancel. I used to just walk back into the
datacenter and flip the power switch, it got me up from my desk, but you can
IPL the drive from the 3584 Web Specialist also.

Subject: Re: TSM backup marked inactive
A few diagnostic questions.
- You said the files are backed up individually (dsmc backup file1) Are
there ever any backups that happen with wildcards or any normal incremental
that happens on the file system?
- Is this directory included in the domain (opt file)?
- Is there an include/exclude file configured?
- could you provide an output of a "dsmc q inclexcl" (maybe the dsm.sys and
dsm.opt while you're at it.
Regards,
Shawn

Besides DataDomain, HP, and IBM, I'm sure the rest of EMC, Oracle, and = even

Sometimes the 'show bfo' is suffiecient and sometimes the 'show invo' is re=

Hello,
Over the years I've saved a lot of commands but never saw one for this. I'm=
not sure if it is possible but I thought I'd ask to see if anyone has it.
Is it possible to create a select command that I input the name of a file t=
hat was backed up and have the output tell me what tape(s) it would be on? = I
have a command that will tell me all the tapes a node has data on, and an=
other to spit out the contents of a tape to a file, and from there search f= or
the filename but I'm curious if there is an easier way.
Thank You
Geoff Gill

If someone pulls a disk out of the array, (replacing a bad disk, etc), you
can't tell a regulator/auditor that it was encrypted. A purely bureaucratic
reason, but still valid.
Regulations pop up all the time without actual technical consideration. (I want
to punch anyone who says the words "7 years" to me!)
The OP's email address sounds like he's involved in the health care industry.
They have the worst of it. Almost as bad as the financial industry.
Regards,
Shawn

Why do you have to have encryption on the device?
No, that wasn't a sarcastic question.
If someone pulls a disk out of your DataDomain RAID, what can they do with it?
Your data is striped across many drives, in chunks that are admittedly large
enough to have a whole mailing address on it. Is someone afraid that someone
else will steal one or more drives and then read unstructured streams of data
looking for PII? Really?
There's no chance that a tape will fall off a truck as you ship your backups
off site. Sure, encrypt the VPN between sites, or use a dedicated network. But
that doesn't mean you have to encrypt your data on the appliance, unless you're
more paranoid than I am (or answer to people who are more paranoid than I am).
At this point, I start worrying more about debacles from poor implementation or
management of encryption than I do about loss of unencrypted data.

Besides DataDomain, HP, and IBM, I'm sure the rest of EMC, Oracle, and even
small brands like Coraid would propose different solutions. For example, why
not replicate cheap disk, on top of which you build FILE devices? Do you need
the cost of a DataDomain or ProtecTier front-end, or do you just replicate
unduplicated data? Oracle and Coraid will sell you large arrays of cheap disk
with ZFS front-ends that could replicate data if you need it and could
deduplicate the data as justified. I'm not saying I'd want to bet my job on
Coraid, but others find there cost advantage over DataDomain attractive.
