Hi all,
My disk space is 100% full.
df -k <dir> -> 100%
One of my debug files consume huge amount of space and i want to remove the same to start off fresh debugs.
However i'm unable to remove the file giving out the following error message:

Hello guys,
It would be so nice of you if someone can provide me with these informations.
1) My SAN group assigned 51G of LUN space to the VIO server.I ran cfgdev to discover the newly added LUN. Unfortunately most of the disks that are in VIO server is 51G. How would I know which is the newly... (3 Replies)
Hi Gurus,
I have to back the /var to other disk, however I am unable to do so. What I did is
Created a partition on another disk, placed file system on the slice and mounted on /mnt .
Issued following command

And I am getting... (2 Replies)
I am running Ubuntu Server, I recently added a new hard drive to the machine
When I run fdisk -l I see both drives.
The recently added drive is present but it's listed as extended.
when I try to mount the drive it says you must specify the file system type.
I can't mount this drive, I was... (2 Replies)
Hello,
Lets say for simplicity that I do not use any vlan config inside my server - one lpar group use hea physical port1, another group hea physical port2. Physical port1 configured as vlan1 on external switch, physical port2 as vlan2.
What is the common practice - should I isolate my vios... (0 Replies)
is there any way to create shared virtual disk between two LPARs like how you can do it using Storage through Fiber on two servers ?

Hello,
VIOS 2.2.1.4 using IVM.
I'm trying to extend a virtual disk assigned to a running lpar so that I can expand the lpar's datavg and grow some filesystems for the user.
Storage admin expanded the lun and new size was reflected in VIO right away. I then needed the storage pool to... (2 Replies)
Hi everybody,
I have Power5 server with 4 internal hdisks each of 70Gb.
VIOS server was installed via Virtual I/O Server Image Repository on the HMC.

OUTPUT(5) File Formats Manual OUTPUT(5)NAME
output - output data file formats
DESCRIPTION
This manual page describes the output formats of the files created by the Yagi-Uda project's output program. The files are ASCII file, so
can be analysed with any graph plotting program.
Example of a .dat File
Below is a typical .dat file, for a 4ele 144-146MHz beam, optimised for a huge (and useless) FB.
# Driven=1 parasitic=3 total-elements=4 design=145.000MHz
# Checked from 144.000MHz to 146.000MHz.
f(MHz) E(deg) H(deg) R jX VSWR Gain(dBi) FB(dB) SideLobes(dB)
144.000 54.7 71.5 44.47 -2.35 1.136 9.386 21.944 16.650
144.500 54.0 70.1 41.34 -0.75 1.210 9.553 27.244 17.153
145.000 53.2 68.4 37.55 1.61 1.335 9.742 103.055 17.777
145.500 52.3 66.6 33.26 5.00 1.530 9.947 25.734 18.547
146.000 51.3 64.6 28.77 9.63 1.832 10.149 18.919 18.919
What is what in the .dat file
The f(MHz) column is the frequency (MHz) at which the data is evaluated at.
The E(deg) column is the approximate 3dB E-plane bandwidth calculated to the nearest 0.1 degree.
The H(deg) column is the approximate 3dB H-plane bandwidth calculated to the nearest 0.1 degree.
The (R) column is the input resistance in Ohms.
The (jX) column is the input reactance in Ohms.
The (VSWR) column is the input VSWR, usually refered to a 50 Ohm input, but this may be changed.
The Gain (dBi) column is the gain at theta=90 degrees, which is the forward direction of the beam. It is possible that a higher gain occurs
at other than 90 degrees, but this is not taken into account. The antenna is seriously at fault if this occurs.
The FB(dB) column is the front to back ratio in dB.
The Sidelobes(dB) column is the minimum level in dB down from the peak gain of any sidelobe. This is not calculated unless the '-c' option
is used, and then only on some optimisation techniques.
Example of a .gai File
The following is a small section of the .gai file.

144.0000 270.0000 -12.5584-21.9444 180.0000 -12.5584-21.9444
What is what in the .gai file
The f(MHz) column is the frequency in MHz.
The theta column is the angle theta, for which the next two columns refer.
The gain-E(dBi) is the gain at theta, relative to an isotropic radiator. This is the E-plane gain. Hence at the peak (theta), this gives
the peak forward gain.
The G(E)-peak is the gain at theta, relative to the peak gain. Hence at the peak (theta=90 degrees), this is zero.
The phi column has nothing to do with the previous 3 columns. It is the angle for which the next two columns refer.
The gain-H(dBi) is the gain at phi, relative to an isotropic radiator. This is the H-plane gain. Hence at the peak (phi=0), this gives the
peak forward gain.
The G(H)-peak is the gain at phi, relative to the peak gain. Hence at the peak (phi=0 degrees), this is zero.
Example of a .up File
The .up file list the improvements made by optimise to an antenna design. Starting from the original design, the file is appended each time
a new better design is found. Here is an example, where the final line is the performance of the 4ele beam with the .dat file shown ear-
lier.
1 7.57dBi, 16.93dB F/B, Z=(31.77-56.34j) Ohms, VSWR=3.95, SL=16.95 dB
84 7.58dBi, 16.93dB F/B, Z=(31.78-56.32j) Ohms, VSWR=3.95, SL=16.95 dB
623 7.58dBi, 16.93dB F/B, Z=(31.78-56.28j) Ohms, VSWR=3.95, SL=16.95 dB
89345 9.74dBi, 103.06dB F/B, Z=(37.55 +1.61j) Ohms, VSWR=1.33, SL=17.78 dB
What is what in the .up file
The first column is an integer specifying the iteration. The other columns, going from left to right are gain(dBi), FB, input impedance,
VSWR and level of the most significant sidelobe, in dB down on the peak gain.
