Hi all,...

...after still having some weird issues with my backup runs not
running as expected (scheduled) running chg-scsi, I was playing
around with the debug files a little, and here's the result (see
attached: "scsidebug"): basically, after "START SCSI_LoadUnload",
messages like

---snip---

##### START SenseHandler
Ident = [ULTRIUM-TD2], function = [generic_changer]
##### START GenericSenseHandler
##### START DecodeSense
GenericSenseHandler : Sense Keys
        Extended Sense                     
        ASC                           04
        ASCQ                          00
        Sense key                     02
                Not Ready
Sense2Action START : type(1), ignsense(0), sense(02), asc(04),
ascq(00) Sense2Action generic start :
Sense2Action generic END : no match for generic   return ->
2/Default for SENSE_ NOT_READY
##### STOP GenericSenseHandler
#### STOP SenseHandler

---snip---

keep filling up my chg-scsi.*.debug log; most of the times the file
itself grows up to 500k just filled with those message. There
doesn't seem to be a way to reproduce why exactly this is happening,
as it doesn't seem to depend on whether the right tape is in drive
or no tape is loaded at all. It also doesn't happen all the time;
sometimes am[check|dump] just run through smoothly without any
trouble at all. I'm currently thinking about several different ways
of dealing with this, including usage of chg-multi instead of
chg-scsi but I wanted to check whether anyone actually has
experiences already running amanda using the following device:

backer:~# loaderinfo -f /dev/sg4
Product Type: Medium Changer
Vendor ID: 'NEC     '
Product ID: 'LL0101H-0A      '
Revision: '0002'
Attached Changer: No
EAAP: Yes
Number of Medium Transport Elements: 1
Number of Storage Elements: 10
Number of Import/Export Element Elements: 0
Number of Data Transfer Elements: 1
Transport Geometry Descriptor Page: Yes
Invertable: No
Device Configuration Page: Yes
Can Transfer: No

I attached a scsidebug output and my changer.conf just in case
anyone might wants to look at it... 

TIA and have a calm friday / weekend anyone...
Cheers,
Kris
