Re: [caiman-discuss] creating extra slices on target disk

Dermot McCluskey Mon, 17 Oct 2011 02:45:44 -0700

Paul,

1)
I've just been trawling through the AI code and
came to the same conclusion as Darren ;)
because you are not specifying the partition type,
they both default to Solaris2/191; the AI code
ensures that the Solaris2 partition is marked as
ACTIVE; then at verification, rather than seeing
that there are 2 Solaris2 partitions, it first sees two
ACTIVE partitions and complains.


2)
See ai_manifest(4) and fdisk(1M) man pages and
/usr/include/sys/dktp/fdisk.h for info on partition
type Ids.
The type value is passed straight into fdisk and that
seems to require decimal-only values for the type,
sorry.

Hi Paul,

The problem here is that you are creating two Solaris partitions - that is
not a supported configuration.

By default, if you don't specify the part_type attribute in the<partition>
tag, it defaults to 191, which is a Solaris2 partition type.

The code is marking any Solaris2 partition type as being the active
partition, and as such you are getting this error.

If you want to create a different partition, you should specify the
partition type, which is not a Solaris partition type[1], e.g.:

        <partition name="2" action="create" part_type="11">

Honestly, I've never seen AI give this error before noticing that there are
two Solaris2 partitions, and giving that more specific error first.

Possibly worth at least a low-priority bug...

Thanks,

Darren.

[1] - http://en.wikipedia.org/wiki/Partition_type - has HEX numbers, we
       require base-10 numbers.

Dermot,

Ok, I can live with that...
But since I'm kind of experimenting with partitions and such, I have some
more questions ....
1) creating more than 1 partition, like:
       <disk whole_disk="true">
         <disk_keyword key="boot_disk"/>
         <partition name="1" action="create">
          <size val="60gb" />
            <slice name="6" action="create" force="true">
             <size val="100mb"/>
            </slice>
            <slice name="7" action="create" force="true">
              <size val="100mb"/>
           </slice>
           <slice name="0" action="create" force="true">
           </slice>
         </partition>
         <partition name="2" action="create">
           <size val="60gb" />
         </partition>
       </disk>
    When I try this, it complains that partition 1 i already marked as "active":

2) Is there a list of partition types (name ->  number), since format/fdisk
only have these:
    1=SOLARIS2   2=UNIX      3=PCIXOS     4=Other        5=DOS12
    6=DOS16      7=DOSEXT    8=DOSBIG     9=DOS16LBA     A=x86 Boot
    B=Diagnostic C=FAT32     D=FAT32LBA   E=DOSEXTLBA    F=EFI (Protective)
    G=EFI_SYS    0=Exit?
you can go to http://www.win.tue.nl/~aeb/partitions/partition_types-1.html,
and I see that 191 (0xbf) is indeed listed. Can I create any part_type I want ?
What is the conversion for the format output to the number used in the
ai_manifest ?
Also, Is the decimal number 191 for solaris required, or can I also use 0xbf ?

Thanks

Paul

Dermot,

Thank you for the answer. The slices within the partition works. I
should have read the 'flagdays' better.
However, for x86, the partitions, if I want to make more partitions,
will it be possible to specify the percentage of the disk I want for the
partitions?

No, sorry.  Partition size should be specified in
a<size>  sub-element, just like slice size (ie not
as an attribute, "..size=50%").
The allowed units are all absolutes: b (byte),  s,
secs (sectors), k, kb, m, mb, g, gb, t, tb, p, pb,
e, eb, z, zb.
If size is omitted for a partition or slice, it uses the
size of it parent (partition or disk).

- Dermot

Something like:
    <target>
       <disk whole_disk="true">
         <disk_keyword key="boot_disk"/>
         <partition name="1" action="create" size=50%>
          <slice name="6" action="create" force="true">
           <size val="100mb"/>
          </slice>
          <slice name="7" action="create" force="true">
           <size val="100mb"/>
          </slice>
          <slice name="0" action="create" force="true">
          </slice>
         </partition>
         <partition name="2" action="create" size=50%>
       </disk>
     </target>

Paul,

Your manifest defines a partition and 3 slices
at the same level under the disk, which is incorrect.
You should either have slices within the partition (x86)
or slices only (sparc).  I would expect this to be reported
as an error, and it may be a bug that it is not.

All,

We run in some very strange issues with b175 when creating extra
slices. It doesn't matter, x86 or sparc. Worked in b151a (well not
with this manifest of course, but the idea is the same)

my ai_manifest.xml part for the the target:

     <target>
       <disk whole_disk="true">
         <disk_keyword key="boot_disk"/>
         <partition name="1" action="create"/>
