Re: LTO 4

Is this library connected to the san via fibre, or the server. What kind of server is it connected to? Have the two drives been connected to each other or are there 2 cards attached to the san or the server? If there are 2 cards in the library, one for each drive, then both will need attaching to the san or server.

Regards,

Jash.
If I can, I will!

Re: LTO 4

Hi,

if you have one FC card from server connected to the switch and both LTO 4 drives as well.
then only thing we can suspect here is zonning.

you should check the following. to get it resolved.

1.Login to the switch , check if both the drives are logged in to the switch (wwn against port)

2 if yes check zonning with server port.

3 If no check connectivity from drive to switch end.

4.NOTE: When you are using LTO4 drives , you should use 1 card per drive to get the performance.

all the best

Re: LTO 4

Hi,

You probably need to update the mapping on the NSR (fibre card) to allow the hosts to see both drives.

Cheers,

Re: LTO 4

1 NSR for 4 drives? This is not enough. Please tell about the cabling!

Hope this helps!
