ioscan -F

[John Mannion]

ioscan -F produces a compact listing of fields
however when run the order of these fields does
not match the order listed in ioscan(1M) manpage.

Anyone got any ideas why or what the correct order is ?

Does this order differ between HP-UX versions ?

Hi,

Can you post a sample of your ioscan -F output, and let us know which version of HP-UX you are using.

regards,

Darren.

I cannot moan, my ioscan manpage (HP-UX 11.00) reports the fields in the correct sequence.

e.g.

# man - ioscan|col -b|sed -n '/Fields/,/follows:/p'|grep -Ev '^[[:space:]]+$|- [0-9] -|\(1M\)'
Fields
The -F option can be used to generate a compact listing of fields
separated by colons (:), useful for producing custom listings with
awk. Fields include the module's bus type, cdio, is_block, is_char,
is_pseudo, block major number, character major number, minor number,
class, driver, hardware path, identify bytes, instance number, module
path, module name, software state, hardware type, a brief description,
and card instance. If a field does not exist, consecutive colons hold
the field's position. Fields are defined as follows:


Compared to one line of ext_bus entries:

# ioscan -kFCext_bus|tail -1
pci:wsio:F:F:F:0:0:393216:ext_bus:fcpdev:1/10/0/0.8.0.255.0:2 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 :6:r
oot.sba.lba.fcT1.fcp.fcpdev:fcpdev:CLAIMED:INTERFACE:FCP Device Interface:6


How are you parsing the output.

If you use Perl there is a CPAN module that could greatly ease the task.
Please, check the HPUX::Ioscan module:

Reading the man page it does state:

I believe that this is a more accurate order than the section that follows.

Its just a poorly phrased man page.
