What exactly did you select in smit (can check smit.script and smit.log for the issued commands)?
What OS level is it (oslevel -s? Seems there is problems reading and writing to the ODM. No clue why it talks about the TCB.
Did it work ever before? If yes, what has been changed on the system?
Just to make sure it is not some effect of Secure by Default (available from AIX 6.1 or higher) - could you also post the output of
if there is any? Thanks.

Hi everybody,
Is it possible to create a Shared Filesystem on Network to be accessed from 2 Systems?
Both systems are AIX but with different versions. One of these systems is AIX 4.3 & the other is AIX 5.2.
Thanks in advanced (8 Replies)
Hi all,
I would like to ask on how to create 2MB partition on a Compact Flash card. It supposed to be of FAT12 type, and the CF capacity is 4GB. I try to do the partitioning and specify the size as 2MB but the partition editor automatically resize it to 8MB. I know that this is possible and the... (4 Replies)

Hello,
How can I add a logic to awk to tell it to print 0 when encountering a division by zero attempted? Below is the code. Everything in the code works fine except the piece that I want to calculate read/write IO size. I take the kbr / rs and kbw / ws. There are times when the iostat data... (5 Replies)
Hello Team,
In a application filesystem, there is a process keep creating the log files. Due to that the filesystem keep getting full. Please let me know how to identify the process which is keep writing in the filesystem.

Hi,
The script below works okay and emails me the log in the end once the script completes but what I'm trying to do is to also notify me via an email as soon as the script encounters any error whatsoever.

Hi,
I have a task of creating a UFS filesystem in an LDOM. It is located in a hypervisor (CDOM).
The storage has been provisioned to the CDOM. How do I make it reflect to the LDOM, and then from there configure/set up the filesystem in the LDOM?
Please help. (1 Reply)

bup-margin
bup-margin(1) General Commands Manual bup-margin(1)NAME
bup-margin - figure out your deduplication safety margin
SYNOPSIS
bup margin [options...]
DESCRIPTION
bup margin iterates through all objects in your bup repository, calculating the largest number of prefix bits shared between any two
entries. This number, n, identifies the longest subset of SHA-1 you could use and still encounter a collision between your object ids.
For example, one system that was tested had a collection of 11 million objects (70 GB), and bup margin returned 45. That means a 46-bit
hash would be sufficient to avoid all collisions among that set of objects; each object in that repository could be uniquely identified by
its first 46 bits.
The number of bits needed seems to increase by about 1 or 2 for every doubling of the number of objects. Since SHA-1 hashes have 160 bits,
that leaves 115 bits of margin. Of course, because SHA-1 hashes are essentially random, it's theoretically possible to use many more bits
with far fewer objects.
If you're paranoid about the possibility of SHA-1 collisions, you can monitor your repository by running bup margin occasionally to see if
you're getting dangerously close to 160 bits.
OPTIONS --predict
Guess the offset into each index file where a particular object will appear, and report the maximum deviation of the correct answer
from the guess. This is potentially useful for tuning an interpolation search algorithm.
--ignore-midx
don't use .midx files, use only .idx files. This is only really useful when used with --predict.
EXAMPLE
$ bup margin
Reading indexes: 100.00% (1612581/1612581), done.
40
40 matching prefix bits
1.94 bits per doubling
120 bits (61.86 doublings) remaining
4.19338e+18 times larger is possible
Everyone on earth could have 625878182 data sets
like yours, all in one repository, and we would
expect 1 object collision.
$ bup margin --predict
PackIdxList: using 1 index.
Reading indexes: 100.00% (1612581/1612581), done.
