Chapter 3. VSE/ESA Support for the RVA
In this chapter we cover several utilities and the VSE/ESA Base Programs that
support the RVA.
3.1 Prerequisites
The RVA has been supported since VSE/ESA Version 1.4 and RVA microcode
level of LIC 03.00.00 or higher. An equivalent microcode level is required for the
StorageTek Iceberg 9200.
To use IXFP/SnapShot and PPRC for VSE/ESA (see Chapter 4, “IXFP/SnapShot
for VSE/ESA” on page 17 and Chapter 5, “Peer-to-Peer Remote Copy” on
page 33) the prerequisites are different from the basic RVA support. The
requirements for IXFP/SnapShot for VSE/ESA support are:
•
RAMAC Virtual Array Licensed Internal Code (LIC) 04.03.00 or higher. An
equivalent microcode level is required for the StorageTek Iceberg 9200.
Note: LIC level 03.02.00 contains support for SnapShot. However, level
04.03.00 introduced nondisruptive code load for the RVA′s microcode and is
the recommended minimum level.
•
VSE/ESA 2.3.0 (5690-VSE) installed with VSE/AF Supervisor with PTF DY44820
or higher.
•
SnapShot requires Feature 6001 for existing 9393 systems or RPQ 8S0421 for
StorageTek Icebergs.
•
If IXFP/SnapShot for VSE/ESA is used in a VM/VSE environment, VM APAR
VM61486 is required for minidisk cache (MDC) support.
For PPRC, the requirements are discussed in 5.1, “PPRC and VSE/ESA Software
Requirements” on page 34 and 5.2, “PPRC Hardware Requirements” on
page 35.
The RVA subsystem provides a set of control and monitoring functions that
extend the set of IBM 3990 control functions. Many of these functions can be
invoked either from the host with the IXFP/SnapShot for VSE/ESA or directly from
the RVA. The Extended Control and Monitoring (ECAM) interface is the protocol
for communications between the host CPU and the RVA. The use of the ECAM
interface is generally transparent to the user.
These functions require that APAR DY44820 be installed and the phase $IJBIXFP
has been loaded to the SVA via the SET SDL interface. Once the phase has
loaded, any of above functions can be invoked through simple operator
commands.
If you want to enable SnapShot on a StorageTek 9200, you must submit an RPQ
to IBM for each serial number.
Before you use IXFP/SnapShot or PPRC for the RVA, we recommend checking
with your local IBM support center to get information about the latest levels of
VSE/ESA, microcode, and required APARs.
