I have a few servers that are all having the same problem when trying to login to their ALOMs. The are T2000's. When I go to login I get the login prompt, but some machines ALOMs aren't responding to the initial login:
You can't type anything after this. It just hangs, and never responds. I can't type the login user name. If I try typing in the login and hitting enter it still doesn't respond. Has anyone else ever experienced this?
No, its not a movie, its a command to get you from the sc> ALOM prompt back to the console or ok prompt.
You must log into the ALOM, then to jump back to the console enter "console -f".
Problem is that this leaves you logged in on the ALOM.
Question: is there an escape key sequence to get... (1 Reply)
Hi guys,
I'm in trouble with a Sunfire T2000.
The OS (Solaris10) is up and running, but I can't log in the sc>I think the terminal server is crashed!
Does anyone know if I can reset the sc> from the OS?
How can I do that?
Thx (6 Replies)
Hi Everyone.
What is the differece b/n ALOM and ALOM CMT Service processor.
I am trying reset ALOM login/passwd using scadm utility on T2000, while I am googling I came cross ALOM CMT doesnt support scadm utility, but ALOM supports.
Not sure how different are these.
Thanks, (0 Replies)
Hi gurus,
I have a sun netra 240 server. I want to get to the ALOM but it always ask for login and password. Can anyone tell me how I can reset the ALOM it to default so I can be able to configure it?
Thanks lots. (2 Replies)
Hello forum,
I have a SUN v250 at home that I have to practice Solaris. I currently have Solaris 9 installed and the ALOM Sun(tm) Advanced Lights Out Manager 1.5.2.
From the ALOM I want to access the console.
sc> console -f
Enter #. to return to ALOM.
after that there is no response.... (19 Replies)
Hi guys,
I'm new with solaris.
I just received sunfire T2000 server.
Problem:
ALOM keep hang/stuck/jammed.
Steps do before it hang :
1. Connect to T2000 (using RJ45 - DB9 cable)
2. Open putty, connect via serial.
3. Power on the server.
4. Its loading.
5. then, hang.

Hi all,
I have some problems with the fan FT0.F0, which looks like has a problem with the PROM/ALOM ( I am nor sure who).....but, in fact, the fan is working properly even in other V440 Sparc Server.
We checked HW comunication between Fan and the MotherBoard, and we think is a problem of... (8 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.
