THANKS.   Dixon Hutchinson/Exabyte provided an LCD projector for WG use.

ADMINISTRATIVE.  The meeting began at 1pm on Monday with attendance and registration. No changes to the January meeting minutes from Boulder were proposed, so the minutes were accepted as submitted.  The proposed agenda was discussed and modified by an evolutionary process throughout the meeting. The meeting ended at 4pm Friday.

DISCUSSION.   The primary purpose of the meeting this week was to come to closure on all open issues.  And as a result, some issues will remain unresolved through this first version of the set of five draft standards.  These will be held as a list of future improvements to the standards.  But it was felt to be essential that the work be limited sufficiently to get to balloting this year.  The only issue left for discussion at the end of this meeting was that of the blind robot proposal (BRP).   Geoff and Curtis will meet in the week following this meeting to conclude discussion of the BRP.

Rough notes of the discussions and issues for the meeting follow...

1. Blind robot support - Weds morning
2. Reservation - batch ONLY. Future reservations addressed later. (30 min discussion)
3. Drive cleaning, cleaning carts - Murali added in DMP. (DONE - see below for details)
4. Slot groups, openport, etc.( 30 MIN discussion)
5. Cart orientation inside a LM. Use side parameter on mount/unmount cmd. Need to store in DB. Curtis - LM respon. (DONE - standard already addresses)
6. STK's new slot handle multiple cartridges. Now tokens must match rather than 1:n mapping (Not to be done before balloting)
7. Att/show turning into get/set in LMP - (DONE - see 5.h)
8. LM/DM model 2-layer name space (DONE - see below for details)
9. I18N Internationalization (Bruce/Geoff has the documentation, 15 min lecture)
10. Allowing cmds while LM/DM in each ready state (DONE)
11. Asynchronous startup of the MMS components needs to be discussed (30-Minutes 3/18).
12. Stuart’s issues
• Fault tolerance (Geoff, check arch doc)
• External agents register for specific policies? NO-RESPON OF ADMIN APP DEVELOPER.(Future)
• Drive Cleaning, Load balancing, Cartridge life cycle, task queue management (External agents and event notification)(Future)
13. Conformance - need to make a general statement. (30 Minute discussion, Geoff will then condense it).
• Can't add additional commands
• New object types for Legato GUI seem OK
• In general, items not explicitly identified in the standards are permitted, but they must not require any changes whatsoever in the components that are part of the standard.
14. Should Diffie-Hillman be added to SSAIP (10-minutes)
15. Security of the where clause (The clauses are at the north pole)
16. Linda's comments about Arch Doc - lots of holes still there. (Geoff and Linda will have a discussion)
17. Drive cleaning. See MMP pg 121 from web 3/12
18. In DB 8.2.1.17 - drive needs cleaning true/false, pushed by DM @ unmount. NEED to check on mount also. Include WHERE clause in MOUNT to allow 1 cleaning app per site instead of 1 per machine. Tri-state (FALSE, ADVISORY, MANDATORY) will be implemented.
19. Event notification (NOT TO BE SOLVED FOR PHASE 1): apps being able to get notification about events in the MMS. Joel s/b like SNMP trap; Curtis/Geoff like DB trigger. Is it CMD-RES or CMD-RES-RES-RES.....
20. (Item 5.h) Single-layer namespace under LM/DM. Name of attribute or value is not part of SSSWG. Up/down is single-layer now. Q: what to attach to, LM or Library object? Should up/down be symmetric? Going up, need to be able to specify LM or Library. This is only for private "scratchpad" information placed by a LM or DM on the MMS. Joel will fix uplink and leave the downlink in LM/DM docs.
21. (Item 5.c) Cartidge type needs max mount count - Joel will add, will default to zero which indicates ignore this value ; this field is advisory from the MMS perspective. Have cart media type "cleaning". We already track number of mounts by cartridge.
• should this be incorporated into the MMS in any way, or strictly left for an admin app.
• how to separate MMS policies and external policies. If in MMS, need way to turn off the policy when external agent is supplied.
22. Joel: inject/eject directly between a drive/port and port/slot.
23. Openport not needed… To be continued?

• Openport has been removed from LMP. Specifics of inject and eject with respect to blind robots are still being Quisanarted.
