How to check disk and lan card status

Carles Viaplana — Mon, 03 Apr 2006 11:33:39 GMT

Hello,

I have to check disk status (ie mirror disks) and lan card status (speed configuration). How can I do it?

In HP-UX I can execute lvdisplay or lanadmin, but what're commands for same purpose in Linux?

Thanks in advance for your help.

Regards,

Carles

lan card status:
"mii-tool" or "ethtool" commands

disk status:
always take a look at /proc/mdstat.
Also use raidtools or mdadm to check the arrays out.
"mdadm --detail /dev/mdX"
"lsraid -a /dev/mdX"

Regards

Shalom Carles,

Your best bets here are ethtool and mii-tool, though mii-tool is broken in certain later RH rleeases.

There is no lanadmin command.

If you install lvm2 in Linux you have most of the lvm commands you know and love with different syntax.

lvm can be used with mirror, any partition except for /boot/

It also has a nice gui that makes adding disk, point and click easy.

Use the ethtool & lsraid commands

Hi all,

Ethernet command ethtool works fine, but commands for disks checking failed:

kathmandu:/etc # df

BTW, here you're OS information:

Thanks in advance for your help.
