No communication between Library and filer.

Hi All,


We have one tape library with 2 tape drives connected with Filer using FCO card.

Library is pingable, FCO card is pingable.

Most likely something between the filer and the library, Cards/ Cables etc ...

First thing, I would powercycle everything, then if no go, you're probably looking at a hardware issue

Library is pingable and FCO card too. From filer and Master server too.

The drives are probably connected via a SAN ? - I doubt they are SCSI connected.

This is not related to 'ping' - I am sure your 'LAN' network connectivity is fine.  You don't have a NetBackup issue you have a filer/ tape drive issue.

The filer is not seeing the drives over the SAN - HBA issue, zoning issue, faulty switch, GBIC issue ...  Does the filer have a command that lets you look 'straight' down the SAN, so a bit like ioscan an in HP / Windows device manager / cfgadm command on Solais etc ...

(OK, these Don;t unite look straight down the SAN but it's the closest you'll get as there won't be any utility for the HBA like there are for servers, eh HBAnywhere/ Sansurfer.
