2230.0. "Multi Robot Control by single DBSBK file" by JRDV04::KO_YOSHIDA (Kouhei YOSHIDA, EJ3/PSC@Tokyo.JAPAN) Thu Mar 27 1997 06:46

o Purpose:
	Execute RMU/BACKUP with four-multi-threading 
	by using two TL820 and SLS.

o Config:
	AlphaServer8400 with OpenVMS V6.2
	HSJ40 * 4
	TL820 * 2
	SLS V2.8A

o Questions:

	1) May I assign same Volume Pool Name to the media that
	   is registerd to different TL820?

	2) If it is able to do,  can SLS control 4 tape drives that
	   is connected to different TL820 by single *DBDBK.COM?

	3) To realize the above, how to config *DBSBK.COM and TAPESTART.COM?

Hi Kouhei,

Yes you can.  If the two TL820 are tied they are treated as one.

Yes it will...if you mean SBK file.

>	3) To realize the above, how to config *DBSBK.COM and TAPESTART.COM?

Something like this will work...

	TAPE_JUKEBOXES := "JUKEBOX1"
	JUKEBOX1 :=	  "node::robot,node::drive1,node::drive2,node::drive3,
			   node::drive4,node::drive5,node::drive6"

where drive1,drive2,drive3 are in the first TL820 and drive4, drive5 and
drive6 are in the second TL820.

Make sure the drives are listed in the order they are seen in the robot...not
necessarily the same as VMS.

2230.2How to config 2 Robots as 1 Jukebox?JRDV04::KO_YOSHIDAKouhei.YOSHIDA@tko.dec-j.co.jpFri Mar 28 1997 05:1028

Ted, Thanks for your reply. 
And I have some additional questions.

Two TL820 are connected to different HSJ40 controller on our 
customer's environment now.  Is it nesessary to change these connection?

I'd like to know how to config two robots as a single pseudo device.
So I read SLS/MDMS V2.8A documents, but could not find descriptions about this.
Please tell me a pointer if I made an oversight.

Robots are established at detatched(but in same room) place now, 
so we cannot connnect them directly by using Multi-Unit Controller(MUC)
and Path-Through Conveyor Mechanisms(PTMs).
Is there other way to combine these as a single pseudo loder?

    No, the Multi-Tower/Multi-Unit configuration is the only one
    that allows you to combine them.
