Chapter 17 Virtual Partitions (vPars)

 A.02.02 supports the SCSI/LAN Combo card as boot device. This card has a built in
PCI-Bridge below the LBA. The full path length for a device is now longer than it was in
A.02.01 and the database was modified to accommodate this.
 The notation to add hardware paths to a virtual partition can be done with the output from
ioscan or the full I/O path with only dots in it. vPars accept both commands and handles them
differently. The database has no delimiter and cannot check which card is present here. The
monitor padded usually six zeros (with a dot to the path) after the first dot. vPars handled the
slashes and dots as the same and vparstatus only prints dots as a delimiter for the hardware
path. Now, the hardware path can reach thirteen elements. Because we can use slashes and dots
in the hardware path, the monitor has the following rule to handle this: Paths with all slashes or
all dots will not be padded.
 A hardware path that contains a dot after one or more slashes may be padded by vPars. In
this case, the element after the last slash is assumed to be the PCI function, so the path will be
padded with zeroes up to six elements after the first dot.
 It is important to specify the hardware path for a combo card or any device in A.02.02 to
a complete ioscan output or with the correct information with all dots.
