Hello all, since one reboot of my Enterprise Backup Server (Networker 7.3)
i'm having this messages in 2 drives of an L20 and an L25 Sun libraries:

Sun StorEdge(TM) Enterprise Backup media: (warning) /dev/rmt/4cbn opening:
DRIVE_STATUS_NEED_INIT
Sun StorEdge(TM) Enterprise Backup media: (warning) /dev/rmt/4cbn reading:
read open error: drive status is The drive is not ready - it requires an
initialization command

Yesterday's half of the backups hanged although there were space to write
to. I've checked index and media databases, so I think there aren't issues
with volumes. It seems Networker is having some strange problems with both
libraries.

I'm afraid that all my weekend's backup will fail, ┬┐does anyone knows where
do that messages come from? messages file and libraries logs are free of errors.
Thanks.

Try shutting down the NetWorker daemons (nsr_shutdown), then when the
daemons are shut down, delete all the files in /nsr/tmp but do not
delete the sec directory.

Then power cycle your tape library.

Then reboot your NetWorker server.

Then after your NetWorker server comes up and finishes the index
checking process, try

nsrck -HEv

I have wondered about this message myself. Since converting to v7.2.2 about
four months ago I get this message every five minutes between the time that
I issue an nsrmm -j -f \\.\Tape0 to eject the prior days tape and the time
that the next days tape is inserted in the drive. This server does not have
a library only a direct attached Tape drive. The message doesn't seem to
effect normal operation only to make this entry in the logs until a tape is
inserted and mounted in the drive.

Hello,
make sure, your Drivers are correct, even if they are loaded and working
make sure you are on as current version as possible, check zoning and
control lun assignment etc to verify if any issues.
Lastly, check and set the CDI flag on the devices to off if its on, this
may or may not correct your problems.

Here is another incident with the DRIVE_STATUS_NEED_INIT error that was resolved without anything too drastic. Running Networker 7.1.2 on Solaris 9 with an IBM 3583L72 library.

The incident began during scheduled backups on a Sunday. By the time intervention began on Monday, Networker was requesting manual loading of several tapes required for pending saves. The needed tapes were in the library, but Networker failed to load them. The tape library LCD reported SAC: 7300 Code: 0x9102. This is a "picker failure." Based on prior experience, power cycled the library. Networker recovered control of 3 of the 4 drives and finished the backups. Networker flagged the fourth drive, 3cbn, in service mode. Monday night's backups succeeded.

On Tuesday, to resolve the state of drive 3cbn, unmounted all the other drives in nwadmin. Found tape #533 in 3cbn. This tape belongs in slot 25, but tape #395 was in slot 25, and slot 2 was empty. Much trial and error failed to get Networker back into a consistent state. Based on what finally worked, recommend this procedure for a similar situation:

1. Use the tape library panel to move the tapes back into their correct slots
2. Run the command
* nsrjb -H
3. In nwadmin, correct Networker's inventory by inventorying the affected slots

Hello,
So did you have the "Picker" arm inspected, sometime it can jam and not
grab the tapes correctly, throwing off Networker, you should pursue a fix
for this, as it's going to come back time and time again.
Also, i typically use nsrjb -HEvvv to reset the library in this type of
situations followed by inventory.

Thanks for the reply. IBM charges us big $$ per visit, so we have an incentive to get it working without them. I suspect it will happen again, and I'm hoping not too often, and that it can be resolved quickly using nsrjb -HE.

I had a similar problem with a non-IBM tape library, which I no longer
use. Every once in a while its robotic gripper would malfunction. As
it turned out, some adjustments were necessary. That library was in
use for several years. Over time, some of the gripper's parts had gone
out of adjustment and it would sometimes miss a slot when it went to
place a tape back in a slot and it would just sit there in front of
the slot, slightly misaligned with it and get into a loop where it
continuously tried to place the tape where it belonged, but fail. Your
library might be in the same situation. If that's the case, you'll
probably need to retain IBM to fix the problem unless you are willing
to try it yourself and have the relevant information available.

I concur. If the picker errors persist, you should call in some type of
service before the thing fails altogether ...
We also had a tape library that was throwing SAC picker/robotic errors
(a Dell rebranded ADIC 60 slot). Since we had it on a maintenance
contract, we called the vendor and they proceeded to replace most of the
robotic components (couple motors, sensors, drive belts, etc.) over two
separate visits. This library had also been in service a couple of years
with very few if any problems until recently. Once the parts were
refreshed and it was re-calibrated, it's been working flawlessly
since... The mechanical parts do wear over time, thus they begin to
loose their original tolerance or precision, and require periodic
replacement or at least a re-calibration ...

Hello,
First of all the problem is hardware and this Tape lib are not easy to
work on, even for an expert, i question the rational of not getting
adequate support on the hardware to begin with, this could jeopardize your
entire backup routine, nsrjb -HEvvv is not meant to replace proper
hardware maintenance and\or support.
Once you start maintaining your own lib, where will it stop, next in line
Z OS and mainframe replacement :}
When the problem occurs in middle of backup there is not much you can do
without disrupting your whole backup cycle, i would talk to management and
get a full support in place rather then trying to fix it yourself.
