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

Hope this helps!

Re: LTO 4

Did you perform the checks suggested by kunalsahoo in the first post already?

Check the connectivity between switch ans server, switch and NSR. Check if the zoning is configured and active. Finally check the NSR mapping again. Does the tape appear as unknown devices in device manager?

Hope this helps!
Regards
Torsten.

Re: LTO 4

You have both drives on the same bus - this is bad performance wise.

Cable like this:

NSR port 1 -> Library controller -> drive 1 -> terminator

NSR port 2 -> drive 2 -> terminator

Do this with power off.

After this, check and adjust the mapping again.

Hope this helps!
Regards
Torsten.
