Configuring and Using the 9900 Subsystem

4.2.3 Defining the 9900 to VM/ESA

®

Systems

64 or Fewer LVIs: To define a 9900 with less than or equal to 64 LVIs to a VM/ESA

®

system,

use the same procedure as for an IBM

®

3990-6, 3990-6E, or 3990-3 subsystem. To define a

9900 with more than 64 LVIs to VM/ESA

®

, enter the LVI address range, storage type, and

sharing option for the subsystem as shown below (the address range varies for each
installation).

[Address Range] TYPE DASD SHARED YES

More than 64 LVIs: To define a 9900 with more than 64 LVIs to VSE/ESA, use the same
procedure as for an IBM

®

3990-6, 3990-6E, or 3990-3 subsystem. For 9900 subsystems with

more than 64 LVIs, the ADD cuu:cuu ECKD statements are the same as for the IBM

®

3390.

Caution: There may be APAR requirements at different versions of the VM software. In
addition, certain requirements apply when VM is supporting guests (e.g., OS/390

®

) that can

run 2105 native. For further information, please refer to the IBM

®

documentation.

4.2.4 Defining the 9900 to TPF

The 9900 supports the IBM

®

Transaction Processing Facility (TPF) and Multi-Path Locking

Facility (MPLF) functions in either native mode or under VM. MPLF support requires TPF
version 4.1 or higher, and RAID-5+ and 3390-3/3R LVIs are supported. The 9900’s TPF/MPLF
capability enables high levels of concurrent data access across multiple channel paths. For
further information on TPF and MPLF operations, please refer to the following IBM

®

documentation:

®

document number GA32-0134-03.

Note on 2105 emulation: There are available PTFs to implement exploitation mode for TPF
version 4.1. For further information, please refer to the IBM

®

documentation.
