Hi Anjaneyulu,

It's all very basic things. You can find blendy of informations on internet. One of the good source is

http://en.wikipedia.org/wiki/Main_Page

Below are the one line explanations.

disk and diskdrive : Both are same which is permanent storage medium to store the data.

Tape: Standalone tape drive which is used to take the backup of data.

Tape catridge: magnetic storage medium which is used in Tape drive to store the data.

Tape Library: is having multiple tape drives, robatic exchanger and slots to take huge data without much interuptions.

From system point of view you can use ioscan command to check those devices

#ioscan -fnC disk
#ioscan -fnC tape

Hi,

Disk is nothing but a Harddisk.
If it's fixed in a seperate unit,it's called as Harddisk drive.

Tape is used to take a backup media and Tapedrive is a drive to detect&check the media.

anjaneyulu,

Usually the drives are where you insert the discs that go into that specific drive, like cd drive, tape drive, hard drive, etc.

A tape library itÂ´s a collection of tape drives managed as a single hardware unit.

Regards,

Jaime.

You have not specified the OS you are using, but since you've posted in HP-UX I take it that you are using some version of it.

You can use the ioscan command to recognize which hardware components are being used in the server.
