bash# /usr/openv/volmgr/bin/vmoprcmd[–up|–down]


To Scan the tape devices:
bash# /usr/openv/volmgr/bin/sgscan tape
/dev/sg/c0t4l1: (/dev/rmt/0): "QUANTUM SuperDLT1"
/dev/sg/c0t4l2: (/dev/rmt/1): "QUANTUM SuperDLT1"


Check on status of drives, tapes in drives/load port/slots:

bash# /usr/openv/volmgr/bin/robtest

The s command is to show something

The slots are "s s #" or "s s" to see them all


The Drives are "s d" The load port is "s i"

The m command is to move a tape


Move from drive to slot is "m d1 s20"


Move from load port to slot is "m i1 s100"


Move from slot to drive is "m s300 d2"


You can also unload a tape if there is a problem with "unload d4"


If the lib has just gone online, you can do a mode command

You can get firmware versions with inquiry command


Do not stay in robtest too long as the move requests could queue while you have control of the robot.

Going through a hard time

I donno what went wrong... Something unexpected happened. Yes, I am jobless for the past one week. Looking for a project. Hopefully I'll get one soon. Monitoring expertise seems like a trash now. One fine day it will help me to achieve something big.

From a Hacker's Perspective

It is almost 5 years, I am out of touch and its time..I decided to refresh my hacking techniques. So ordered a book(Network Security: A Hacker's Perspective) and started reading it. This book has basic information about network security tools.

Once I am done with this book... thinking of buying the following books of Kevin Mitnick

The Art of Intrusion
The Art of Deception

One should think in security perspective when he/she runs their server on the internet. I guess, I reached that stage now. So I am here and wanted to protect my servers from attacks.

Always think from a hacker's perspective, find the security issues and fix them... this is one of the best approach I learnt.

A Perfect Repartee by Sachin Tendulkar

We all know about Sachin Tendulkar who is one of the best batsman in the cricket world. After India's biggest news paper asked the question: Tendulkar? or Endulkar?... He did not respond for this question. Instead, He simply concentrated on his game and responded with a bloody-minded-amazing century in ODI at Peshawar.

I guess the pacifist in him put an end to it with a repartee of amazing 100 runs. We heard about the quote "Action is Eloquence". Sachin proved it.

The little master is back to form now.

Space Elevator

How good If we travel in an elevator to go to space. Bremerton, WA, based company Liftport is working towards a goal of building a space elevator.

The purpose of this elevator would be for sending cargo and astronauts to the international space station.

Aamazing Mattingly drawing of what the future could look like.

Act Upon Music in the Data Center

Sheridan College Institute of Technology and Advanced Learning has created software that translates network and server activity into music. This means the data center operations team will listen to a steady flow of music and when they listen a sudden string of violin that means SPAM is flowing around. They call it as information music iSIC.
