Table IV. Hardware Path Specifications
Beginning with vPars 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 whose sequential digits are
4010000, 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 Virtual Partition Manager or the command-
line interface.
When entering a hardware path, the sequence and number of slashes (
/) and dots (.) in the hardware
path that you input determines the resultant hardware path as follows:
What the vPars commands will

one or more occurrences 0/1.
of both / and . Path will be padded
1/0
only / used 1/0/1
Path will not be padded
1.0
only . used 1.0.
In the above table, padding means to pad using ".0" up to six elements after the first dot. For the example
shown in the first line of the table, the resulting path, as displayed by vparstatus
, will be
0.1.0.0.0.0.0.0.
EXAMPLES
If a path was entered using slashes and dots 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
vparmodify -p winona2 -m io:4/0/1/0/0.0.0:BOOT
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
vparmodify -p winona2 -m io:4.0.1.0.0.0.0:BOOT
To change the above path to be the ALTBOOT setting, the command is
vparmodify -p winona2 -m io:4.0.1.0.0.0.0:ALTBOOT
Using vPars A.02.02, when setting a path, you can either use one or more occurrences of the
/ and . in
the path so that the resultant path is the correctly padded path (this path is the same as the path shown in
the
ioscan output) OR use the exact path, correctly padded, using only dots (this path is the same as the
path shown in the vparstatus output).
In the former case above, the ioscan output for a combo-card (combination of SCSI and LAN PCI card)
may show
disk 0 12/0/8/0/0/4/0.0.0 ... SEAGATE ST39103LC.
Then, the vPars command would be
vparmodify -p winona2 -a io:12/0/8/0/0/4/0.0.0.
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 according to the table above. Subsequently, the
vparstatus out-
put 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
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
12:0.8.0.0.4.0.0.0.0.0.0.0 BOOT. Then, the vPars command would be
vparmodify -p winona2 -m io:12.0.8.0.0.4.0.0.0.0.0.0.0:ALTBOOT.
