ACSLS Silo

Question

Hi,

I need to install a SGI Irix server to use Storagetek SL500 ACSLS silo with 2 DLT drives. I wanted to know should I run jbconfig on the backup server and should the robotic be visible on the backup server.

I hope running inquire on backup server should show me the robotic along with the 2 drives. How would NW detect the slots to be configured for NW?

Regards,
Anuj

If this is ACSLS contolled library you don't care about robotics as it is not NW that it controls it. So, you don't require robotics to be visible to NW server.

You run jukebox configuration from the backup server.

Anuj, I believe it is time to read some docs first.

Slots you allocate - read nsrjb manual. You allocate slots as you define volumes.

You may or you may not need to configure few bits on ACSLS - this really depends on your setup and usually it is done by Sun/STL people. Usual bits are volume pools (unrelated to NW pools), firewall options, cleaning, etc...

How do I get the slots configured?Also, do I need to specifically configure/check anything on the silo management software?Regards,Anuj

What I need to know is like in any SCSI or Fibre
library, jbconfig automatically detects the no. of
slots available.

No.

In ACSLS, since this is controlled by silo software,
how does NW come to know how many slots are assigned
for it and how to use them.

You must allocate them via nsrjb command.

Whomever the admin is for the ACSLS server, he/she will allocate slots/tapes for your backup server. For example, say you are given 100 slots with tape labels 00001 - 00100. Then you can add them all at once or just a few at a time like this:

nsrjb -vaT 00001-00010

This will then create 10 slots with tape volumes 00001-00010.

Yes it is strange when you are used to the non ACSLS/Silo way...slots are created when you add new volumes to your Silo.

Why are you using ACSLS for such a small SL500 library? We have the same library direct attached.

Overall the Silo will have 189 slots. Of this 50 would be allocated for Legato for backups and the balance for HSM application. The primary data is on Fibre disks which is staged on to SATA disks and Silo tapes using an HSM application. Netwoker backs up data when it is on Fibre plus data frm other servers in the environment.

I just attempted and found out that if multiple slots have alphabets nsrjb should have different syntax. Ex. if barcodes are from ABC001 to ABC010, nsrjb syntax should be - nsrjb -a -T ABC/001-010.

Thanks for your help.

Yes, that's all very well documented in nsrjb manual and there are examples for it. It applies whenever you wish to allocate volume to NetWorker (SmartMedia, AlphaStor and silo management).
