Beginning with vPars version A.02.02, the way to specify hardware paths has changed. This was done so that older vPars configuration databases remain compatible with additional hardware that is being supported. For example, given a path where its sequential digits are 4 0 1 0 0 0 0, it is not possible to determine whether this path means a device at "4/0/1/0/0.0.0" or a device at "4/0/1/0/0/0/0.0.0.0.0.0.0". The former structure is cell/sba/lba/dev/function, and the latter structure is cell/sba/lba/pci_bridge/dev/function where pci_bridge has the format m/n. Therefore, the following rules have been created. These rules apply when using either the vPars GUI or the command-line interface. When entering a hardware path, the sequence and number of
slashes (/) Table 3-1 Hardware Path Format Rules
In the above table, padding means to pad using .0 up to six elements after the first dot. If a path was entered using slashes and dots and while using pre-A.02.02 software, you cannot enter the same path format using A.02.02 or later software. You must enter the path using the exact same digits but with dots instead of slashes as delimiters. For example, if a path using A.02.01 software was entered as:
then vparstatus would show the path as "4.0.1.0.0.0.0". To do the same vparmodify command above but using A.02.02 or later, the command would be:
To change the above path to be the ALTBOOT setting, the command is:
Using vPars A.02.02, when setting a path, you can either use
one or more
Then, the vPars command would be
Note that this path of 12/0/8/0/0/4/0.0.0 becomes correctly padded to 12.0.8.0.0.4.0.0.0.0.0.0.0, in accordance to the table above. Subsequently, the vparstatus output would show this path as 12.0.8.0.0.4.0.0.0.0.0.0.0, which can be used if you wish to cut and paste the path as in the command "vparmodify -p winona2 -m io:12.0.8.0.0.4.0.0.0.0.0.0.0:BOOT". In the latter case above, the vparstatus output for a combo-card may be:
Then, the vPars command would be:
