Hi Guys,
This is my first post in Linux forum. Also I am new with Linux enviornment. I have a few basic questions regarding configuring my linux.
How do i detect what HBA is installed in my Linux host and see its firmware and stuf? I mean from command line?
How do i discover all the Hardware and Storage disks that are connected to my system? Again from command line.
How do i format and partition the disk using linux command ?
Also whats the command to see gateway configured in my system ?
Any document explaining Linux administration will be of much help to me.
Thanks in advance for all the answers.

Solution
1- Normally you use a utility privided by the HBA vendor, for example, qlogic provides SanSurfer.
2- You can resiscover devices in several ways, see:
http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=1136273
3- First, create a partition with fdisk or parted commands, then format with "mkfs -t ext3"
4- You can see your gateway with netstat -nr, check the 0.0.0.0 destination.

Por que hacerlo dificil si es posible hacerlo facil? - Why do it the hard way, when you can do it the easy way?

Re: Linux basic administration
Thanks for the post. I have not understood the follwing part in device discovery...
echo "1" > /sys/class/fc_host/hostXYZ/issue_lip
echo "- - -" > /sys/class/scsi_host/hostXYZ/scan
what host xyz stands for ?
echo "1" > /sys/class/fc_host/hostXYZ/issue_lip
echo "- - -" > /sys/class/scsi_host/hostXYZ/scan

How do i format and partition the disk using linux command ?
]# fdisk /dev/emcpowerc
The number of cylinders for this disk is set to 8802.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
