Hi i 've a M5000 running 2 domains in my Lab with following hardconf
Now i want to partition the 2nd domain further to create a 3rd domain with equal resources on both 2nd and 3rd. For that i set the XSB to quad mode and created the 3rd domin. But now the 3rd domain does not have any network interface and no HDD and the 2nd domain has been deprived of HBA cards. Is it possible to move one HBA card from 3rd to second domain and one network interface from 2nd to 3rd domain ?
Hi,
I 've a fully loaded M5000 which i would like to partition in 4 domains but i have a concern that since we have only 4 internal disks how can we partition the box in for domains with 2 disks ( mirrored ) in each domain. Should i go ahead with 1 Lun from SAN and 1 internal disk for each of 4... (3 Replies)
Hi all
A couple of new M5000 servers will be arriving soon and I need to work out how to configure the underlying domains.
It will come with 4 x CPUS, 32 Gb of memory, 4 x HD, 2 x IOtrays.
Reading the XSCF manual, I can configure the item into 2 domains, something about uni / quad xsb.... (9 Replies)
I have an M5K with disk issues I'm trying to troubleshoot, and it's causing me some confusion. I know the host has four on-board HDDs, but the format command's output shows c0t0d0, c0t1d0, c3t0d0, and c3t1d0. cfgadm -al shows c0t3d0 as the DVD-ROM drive, and c1 and c2 as SAN disks. Confused yet?

Hi
We have an M5000 with one domain running Sun Cluster on it. We would like to split the domain into two domains. One with the existing Sun Cluster and one with a fresh install. We have 2 CPU Boards (8 CPU) / 4 Mem Boards (64 gb memory) and 2 IOU as well as 4 disks
Is it possible to have... (9 Replies)

I took over an M5000 and have a jumper server with a nic to connect to the console IP of an M5000. access via ssh user@ip.
it was working fine, another person can connect remotely on the subnet, but when I ssh,it just hangs and then times out.
so my question is,
any ideas of what I might... (4 Replies)

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.
