trouble using 2 drives in one library
Locked
 
|
Hi MH,
Thanks for the great VTL. I've been using it (v 1.5.0) for a few months with 1 drive in a library with no problem. Very fun. I am now trying to add another drive to the library and mtx is having difficulty moving tapes into one of the drives. My configs: -------------------- /etc/mhvtl/device.conf VERSION: 5 Library: 10 CHANNEL: 00 TARGET: 00 LUN: 00 Vendor identification: STK Product identification: L700 Unit serial number: XYZZY_A NAA: 10:22:33:44:ab:00:00:00 Home directory: /ceph/tibs/root/mhvtl/ PERSIST: False Backoff: 400 Drive: 11 CHANNEL: 00 TARGET: 01 LUN: 00 Library ID: 10 Slot: 01 Vendor identification: IBM Product identification: ULT3580-TD5 Unit serial number: XYZZY_A1 NAA: 10:22:33:44:ab:00:01:00 Compression: factor 9 enabled 1 Compression type: zlib Backoff: 400 Drive: 12 CHANNEL: 00 TARGET: 02 LUN: 00 Library ID: 10 Slot: 01 Vendor identification: IBM Product identification: ULT3580-TD5 Unit serial number: XYZZY_A2 NAA: 10:22:33:44:ab:00:02:00 Compression: factor 9 enabled 1 Compression type: zlib Backoff: 400 -------------------- -------------------- /etc/mhvtl/library_contents.10 Drive 1: Drive 2: Picker 1: MAP 1: Slot 1: TIBS1000L4 Slot 2: TIBS1001L4 Slot 3: TIBS1002L4 Slot 4: TIBS1003L4 ....

mayby you have to define also MAP 2
my config (with 3 drives): Drive1: Drive2: Drive3: Picker 1: MAP 1: MAP 2: MAP 3: Slot 1: M00001L5 Slot 2: M00002L5 Slot 3: M00003L5 .......... etc. ..... |

Many thanks for the bug report. The bug report is actually opposite to your reported behaviour. The one-drive config should not have worked !On Thu, Aug 14, 2014 at 1:17 AM, cwseys [via mhVTL - A Linux Virtual Tape Library] <[hidden email]> wrote: Hi MH,

Hi Mark,
> The bug report is actually opposite to your reported behaviour. The > one-drive config should not have worked ! I think my mentioning a working 1 drive tape library might have confused things a bit. The problem described was for a 2 drive tape library. (2 x ULT3580-TD5 with *L4 barcoded tapes) The commands show first an mtx command failing to load a tape into Drive 1. The next mtx command successfully loading a tape into Drive 0 (using the same tape library). BUT WAIT! I think I found the problem: Both of the drives have "Library ID: 10 Slot: 01". The example config the 2nd one says "Library ID: 10 Slot: 02" . I think I've been trying to ram a drive into an already occupied slot! Oh boy, gonna try that fix!

Looking at the post with a computer & real browser (rather than a phone).. Seeing my mistake. You're good on this front. Yep - that will do it. The config you posted initially has two drives configured as belonging library 10 and to slot 1.
