>>Partition name <<<<<

what do you mean by partition name ? Can't understand your Question , there is no partition name , do you mean HPUX Operating file system layout has partition name ??

command => bdf -> to display all mounted file system

Partition size ?

command => lvdisplay
man lvdisplay

take note , use should use above command for all the partition or file system mounted by refering to bdf command out put


Is boot Partion ? -> not able to understanding the question

Mounted location of partition

you need look for below link -> you can understand some basic commands related to your Questions

Example:

# idisk /dev/rdsk/c0t6d0

Size is usually default:

p1 500MB
p2 100% of remaining space
p3 400MB

[Torsten.]

As said

p2 named hpux
p3 named HPSP 400MB

I am getting the following error when I issue idisk command

idisk /dev/rdsk/c2t1d0s2
idisk version: 1.31
idisk: Primary partition information not valid.
Run idisk with -r option to restore.

[Torsten.]

Try

idisk /dev/rdsk/c2t1d0


"s2" is already the second partition, not the disk itself

[DeviPvk]

Thanks for the reply Torsten.

It worked. But I have a doubt regarding the partition details. when I issue following command on my machine

ioscan -funC disk

I am getting the result as follows

How to get lvpath for lvdisplay command?


thanks,
Devi

[Johnson Punniyalingam]

what exactly /dev/dsk/*** and /dev/rdsk/*** mean?

c=controllor
t=terminal /target
d=disk
s=slice

/dev/dsk/c2t1d0 -> disk has been sliced with 3 slices that why you see

/dev/dsk/c2t1d0s1 /dev/rdsk/c2t1d0s1
/dev/dsk/c2t1d0s2 /dev/rdsk/c2t1d0s2
/dev/dsk/c2t1d0s3 /dev/rdsk/c2t1d0s3

How to get lvpath for lvdisplay command?

lvdisplay -v /dev/vgxx/lvolxx |more

man lvdisplay for more information

[Torsten.]

The raw/"cooked"/block/character devices are used to get access to disks in different ways.
There are many highly detailed explanations available on the net.

About volume groups:

Use
# vgdisplay -v ...
to get information about the volume group (including LVOLs).

With this information get closer to the LVOLS:

# lvdisplay -v /dev/vgxx/lvolx

[Torsten.]

BTW, this is the disk layout of a Integrity boot disk:

thanks for the links

Does every disk have these 3 partitions
P1 EFI,
P2
P3 HPUX?

[Torsten.]

Every boot disk in Integrity systems.

[Andrew Rutter]

hi,

only boot disks on integrity systems have these partitions.

normal disks used for storage just use volume groups and logical volume groups, just as boot disks on PA risc servers.

but the partitions are as Torsten stated not your example

[Russ Park]

This question has generated a wealth of good replies and information. I'm simply curious what real use you have for the partition information? I've worked with integrity boot disks for years now and can't think of a time when I 'needed' this information. I understand curiosity, but as to the disk layout, not sure what stirred you to ask the initial question in the first place?

Thanks,
Russ

Hi

you can do

isocan -fnCdisk
there note teh disks in the format of /dev/dsk/cXtYDZs*
then do
diskinfo /dev/rdsk/cXtYDZs1|awk '{ print $1 /1024}'
diskinfo /dev/rdsk/cXtYDZs2|awk '{ print $1 /1024}'
diskinfo /dev/rdsk/cXtYDZs3|awk '{ print $1 /1024}'

to get the sizes of teh partitons in MB

Hi
No points please: only correcting the last post.


diskinfo /dev/rdsk/cXtYDZs1|awk '{ print $1 /1024}'
diskinfo /dev/rdsk/cXtYDZs2|awk '{ print $1 /1024}'
diskinfo /dev/rdsk/cXtYDZs3|awk '{ print $1 /1024}'


please replace these with
diskinfo -b /dev/rdsk/cXtYDZs1|awk '{ print $1 /1024}'
diskinfo -b /dev/rdsk/cXtYDZs2|awk '{ print $1 /1024}'
diskinfo -b /dev/rdsk/cXtYDZs3|awk '{ print $1 /1024}'
