External SCSI drive

External SCSI drive

External SCSI drive

I've just bought an external HP Ultrium SCSI tape drive.  I'm plugging this into a HP Proliant ML370 server.  Question is simple - do i have to shut the server down to connect the drive up?

Apologies if it's a stupid question - have been in the IT industry for 16 years but i've never had to use an external SCSI connector up to now!


RE: External SCSI drive

Depends on the OS and how old the OS is.

Electrically, connecting and disconnecting external SCSI cables can be iffy if there's any local static problems. Ground yourself thoroughly before trying.

RE: External SCSI drive


Well, I would generally not recommend this.   There are internal termination within the system.  

This could especially be a problem if the Newly installed device has the same SCSI ID as something currently running.  

Other than that, I would make sure when you plug the drive into the server, it is off.  

After connections are made, I would turn it on.  

Then I would bring up the Array utility and have it search the scsi chain.

This way, the server will now see all devices on the SCSI bus.

Now, I would image, your software like BE or Arcserve will see the tape
drive and  you can use it.  

To play it safe, I would shut the server down and install it.
Safer that way and only takes a few minutes.   Better safe than sorry.
