I don't have Linux systems with physical-connected SAN anymore, but just to give you a direction - lsblk shows, which logical volume lays on which disk. Then you can use e.g. lsscsi to find the WWNs.

I would guess, rmmod lpfc followed by modprobe lpfc. My previous warnings and caveats still apply.

Depends what changes you are making. Could be as simple as rmmod-ing and modprobe-ing the relevant modules but that could be disastrous if you happen to be using those things at the time.

Try:
reset command
revoke redirection
new shell

Hi,
one reason could be messed up terminal line settings.
This can often be fixed by:
stty sane

Note that before you try stty sane, you will need to be at a command prompt. Depending on how you got into the messed up state, you may be able to get to a command prompt by typing in ctl-c or ctl-j...

Is that all? You can ignore that. How many blocks it takes is very filesystem-dependent, and CD/DVD filesystems are strange enough a hard drive filesystem is going to be radically different.

If...

Size of what? The size of a folder in ls is filesystem-specific, and not really meaningful. Directory entries on a CD/DVD are very different from on a Linux partition.

If it was me, I would write a PHP script to do this. Basically you would have a configuration file with the hostnames and other required information; then you can write a PHP script to read the...

Have you tried somethin like clusterssh? Altough more than 200 servers are a lot even with a tool like that.

While this won't help for all tasks you might want to achieve, you should consider some centralized administrative repository for user management, like NIS or LDAP. Adding or modifying user's account...

If you put the public SSH key on each of the servers, then you will be able to have password-less authentication to run the commands. Do you know how to generate the keys and what to do with them?

If the modules are pure Perl, simply extract them in $HOME/perl-lib and add $HOME/perl-lib to the PERL5LIB environment variable, or if you wish to provide a site wide install, as root extract them...

the standard way is to use h2xs to create an installable package.

Just spun up a CentOS box to check, and you're right, the box does boot, you just can't do much with it as it does not have anything mounted filesystem-wise.

The good news is that you could...

It may be preventing you from logging into the GUI as root because doing so is a really bad idea.

Create a limited user and put it in the 'wheel' group. Try and log in as that. It won't be root...

1. No.
2. Yes but not all (see the list on the wine site).

Install WINE and click on your windows application distributive.

Many distributions do not allow direct root access; it's a security measure but you can modify these settings in /etc/pam.d/gdm and /etc/ssh/sshd_config

What type of wireles card do you have (run...

Hi.

There's nothing absurd about it, really.

a, and s have no special meaning. Single quotes have no special meaning inside double quotes, # doesn't have special meaning inside any quotes,...

There's not a magic "make-flash-drive-act-like-bootable-CDROM" program; even if you fooled the BIOS somehow, everything'd break down the instant things started loading device drivers. It's possible...

An optical drive uses completely different components to burn CD's than DVD's so a CD might still work if you can burn one.

You could try a usb stick.

Does the CD read OK in windows? (is this a media or drive problem?)

Hi.

See: http://en.wikipedia.org/wiki/Flag_(computing)

Google and Wikipedia are your friends for factual information ... cheers, drl

Interesting question. I am not sure that there is a precise definition.

Typically permission flags refer to constants defined to represent corresponding permission bits and are used for code...

I guess you need to unzip it at first.

Also consider :
file smthing.tar.bz2-00This may give some clue about the format of the smthing.tar.bz2-00 file.
If it comes from somewhere else, make sure...
