you've to give the ilom a ip with dhcp or a static one via the serial port. on the serial port login to the ilom with root and the default password. if you don't know the default one, i'll send it to you via pm, just ak. after login to serial console type:
and you'll come to the "ok" prompt after the post. to setup network with static ip go to "cd /SP/network" and do all needed settings there!
Hi all,
I have just replaced the HDD on a Ultra 5 Spark machine, now I need to reinstall Solaris 9.
The problem is: how do I get to the OK prompt without a Sun keyboard in order to boot from CD?
At moment when I power on the machine I get the following error:

Hi,
I need configure this server for two zones (oracle and glassfish). Server has 2CPU 8cores = 128vcpu and 16 GB RAM.
I am interested in mainly the division of the processor and memory.

Hi all,
I use latest bind 9.6.1, brand-new T5140 Sun Server, 10u8 Solaris OS, Mar-2010 OS patch to configure a caching dns server.

Hi All,
We have a T5140 server which has 128 threads in total. Is it possible to reduce the number of threads per core through some configuration changes? I am sorry for being so naive but I am one on this.
Why would I like to do this? Unfortunately we have this for an Oracle Database Server... (6 Replies)

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.
