RDEVMAP .CMD OS/2 Utility
The following options are used to start VM and can be used only with VM/ESA:4
WARM
Only try to warm-start the VM system.
CKPT
Try a warm start, but try a CKPT if warm fails. This is the default.
Note: For VM/ESA (ESA Feature), WARM and CKPT options are
identical.
NOAUTO
Do not automatically answer VM questions during IPL.
IMAP
devmap
This option issues the AWSPROF command to switch to this DEVMAP before starting
the P/390 I/O subsystem. This option has no effect if the P/390 I/O subsystem is
already running. First stop the P/390 I/O subsystem by selecting the
END
P/390 icon.
Then issue the IPL command.
IMODE
mode
The architectural mode, either 370 or ESA.
IPARM
loadparm The load parameter specifies a 1- to 8-character load parameter. If fewer than eight
characters are specified, the load parameter is left-justified and padded with blanks.
The load parameter can be retrieved by the operating system during its IPL sequence.
Its use is determined by the operating system, such as indicating the nucleus to be
loaded during the IPL sequence.
INOCLKGET
This parameter stops the OS/2 clock from being read and leaves the S/390 clock as
UNSET. This parameter is useful for testing year 2000 solutions.
INOCLKSET
This parameter specifies that the S/390 TOD clock is set, it should not write to the
OS/2. This parameter is useful for testing year 2000 solutions.
INOCLKCLR
This parameter specifies that the S/390 TOD clock will not reset on a CLEAR-RESET.
This parameter is useful for testing year 2000 solutions.
Example
IPL 300 CLEAR /MAP D:\VMESA\DEVMAP.IVM /MODE ESA /PARM 0200
This command IPLs device 300 (as defined in the specified DEVMAP) in ESA/390 mode and passes the
IPL console address 0200 to VM. Specifying the /PARM option to VM/ESA causes the VM/ESA Stand
Alone Loader (SALlPL) screen to be displayed and it allows you to specify which CP nucleus file you want
to IPL.
RDEVMAP.CMD OS/2 Utility
RDEVMAP reconfigures a DEVMAP. It is used during installation of the Starter System, but can also be
used when reconfiguring a system. Instead of using the P/390 Configurator to change DASD volume
locations interactively, you can use RDEVMAP to make mass changes to the volumes.
• For VM/ESA (370 Feature), the operator console must be defined as a 3215 to use these options. If these options are
specified, they automatically answer NO to the TOO clock question and then answer the
WARM, CKPT, FORCE, COLD message
as either WARM or CKPT.
• For VM/ESA (ESA Feature), the operator console must be a TCP/IP attached 3270 to use these options. If these options are
specified, they automatically press ENTER for the TOO clock question and also press ENTER for the WARM, FORCE, COLD
message (which implies "warm"). If a FORCE start is necessary, then one will be performed unless the NOAUTO option was
specified.
