We currently have a sysplex with 5 LPARs where we run the View and View EAS tasks on one of the LPARs (the primary LPAR). If a user on the primary LPAR browses a report that's been archived to tape, EAS mounts the tape and presents the report and the user does not need MOUNT authority. If a user on one of the secondary LPARs tries to do the same thing they get a 'No mount authority' message and cannot view the report. Is there a way to configure EAS so that a user from any of the LPARs can access an archived report without needing TSO mount authority? Do we need to have an EAS task on each LPAR? If so how is that configured?
Release : 14.0
Component : CA View
Expanded Access Server
The cause of the "No Mount Authority" message was due to not having a secondary EAS task running on the LPARS the reports were being browsed from.
* Key points to remember:
- ONLY a TYPE=PRIMARY EAS task can mount tapes.
- A single TYPE=PRIMARY EAS task supports tape mounts for multiple View databases. This PRIMARY task would run on the system where the tapes and tape drives, to be mounted for View, are available.
- Technically, you don't link an EAS to a View database. Instead, you link a View database to it's appropriate EAS task, via the View databases (EASTNAM1, EASTNAM2 or EASTNAM3) SARINIT parameters.
* Different configuration options:
- If you have say 2 View database running on the SAME LPAR and you want EAS to mount tapes for BOTH of these View's, then all you would need is a single PRIMARY EAS task running on that LPAR. You would then link both of the View's to that same EAS task via "EACH" View's SARINIT EASTNAM1= initialization parameter.
- If you were to run multiple Views on any other LPARS, then as long as those LPARS have an XCF link to the PRIMARY EAS task, you could install TYPE=SECONDARY EAS tasks on those other LPARS. These SECONDARY EAS tasks could share the "SAME EASTNAME" as the PRIMARY task, and the View's EASTNAM1= parameter would be configured accordingly. (The SECONDARY's are linked to a PRIMARY via the EASTNAME specified for that EAS task).
- You could run TYPE=PRIMARY EAS tasks on EACH of the LPARS that you run View's on, if you wanted each View to have it's own tape server. In this circumstance, each EAS task would have a unique EASTNAME and you would configure each View's EASTNAM1= name accordingly.
