3.4.3 Startup/Shutdown
System startup
The Initial Program Load (IPL) of OSD/XC is triggered in the X2000
Carrier System with the "KVP Console" application. The KVP main
function menu is activated with the "F2" function key after logging
on to a console ID in the X2000 Carrier System.
The KVP commands are available to you after selecting the menu item
"SVP Commands".
A form for starting BS2000 is opened by selecting "ipl - start
BS2000". The following IPL parameters can be specified:
- IPL load device
specifies the mnemonic device name of the IPL disk
- Console device
mnemonic device name of the console write path. This is
set to Z0 in the preinstalled system.
- IORSF level
the IORSF level (0-9) can be entered here if channels are
connected.
If no IORSF level is specified, the setting from the last IPL
is used. All available IORSF levels can be queried with the
"iorsf" menu item in "SVP Commands".
- ipl parameters
defines the type of system startup:
d Dialog startup (default value)
f Fast startup
a Automatic startup
- BS2000 system name
If available, the IOCONV-name is taken from the IORSF for the
selection of the BS2000 parameterfile
SYSPAR.BS2.<ver>.<IOCONVname>.
In X2000 V3.0 this function is implemented via the IPL system
name parameter, if there is no IORSF available.
- Delete BS2000 memory (y,n)
You can delete the BS2000 memory with this entry.
Note:
If BS2000 has already been started, an additional point "BS2000 is
already running ..." appears for safety reasons with the IPL func-
tion.
You will find further information in the manual "SX Series Busi-
ness Server, Operating and Administration".
3.4.4 Using VM2000
With guest systems on servers from the SX100 series that only con-
tain internal SCSI disks, it is recommended to use the software
caching product DAB with around 0.3 GB buffer in main memory.
When backing up data with HSMS/ARCHIVE, you should note that the
CPU requirement for local backup in BS2000 is approximately 1 RPF
per MB/s. If the full CPU performance is not available during the
backup, e.g. because CPU utilization is limited on the guest system
(Max-CPU-Utilization), a lower transfer rate is to be expected to
the magnetic tape unit (LTO1,LTO2).
