4. If you are IPLing CP from an FCP device (SCSI disk), PDVOL=raddr must be
specified as an IPL parameter. Any device address that is not in the I/O
configuration of the system to be IPLed can be specified for raddr. CP requires
this parameter in order to build the EDEVICE control block for the SYSRES /
PARM disk device during CP initialization.
5. Attention: As of z/VM V5R1, the number of blocks on FBA DASD (SCSI or
not) that SALIPL uses for SAPL has increased. SALIPL writes to blocks 5-207
on CP-formatted DASD. In previous releases, SALIPL wrote to blocks 5-31. You
must ensure that no other functions, such as CP directory, warmstart,
checkpoint, paging, spooling, or minidisks, are using the area to which SALIPL
writes.
On a CMS minidisk with a RECOMP area, SALIPL writes SAPL to blocks 5-207
of the RECOMP area. In previous releases, blocks 5-31 of the RECOMP area
were used. In order to accommodate the larger size of SAPL, you may need to
increase the size of the RECOMP area on the CMS minidisk.
The following data is in the blocks that SALIPL writes out:
Blocks 5–196 SAPL program
Blocks 197–199 Reserved for IBM Use
Blocks 200–207 SCSI boot records
If you want to install SAPL on device 0400, a full-pack minidisk to which you have
R/W access, and you want SAPL to use the CMS-formatted minidisk that is 210
cylinders into the full-pack minidisk as the disk from which it will read a module, you
enter this command:
salipl 0400 (offset 210 module cpnew iplparms fn=sysnewVOLUME ID IS ESARES
MINIDISK VOLID AT OFFSET 210 IS PARMD1
Ready;
The parameters entered on the SALIPL command specify that SAPL should look for
a module called CPNEW on the CMS-formatted minidisk and should pass the IPL
parameter fn=sysnew to the program when it is loaded.
