Does the media server require fiber access to the EVA and the MSA also?
Solved! Go to Solution.

Solutionit would be sufficient if you put the HBA of the server and the port of the MSL into one zone. If more then one server should access the MSL, just add the HBAs of those servers into the zone. You don't need a zone which contains the MSA, EVA and MSL ports.

Re: MSL2024 Zoning best practice
Multipathing doesn't work with the Tape Library, you need to change the pathes manually, if a path failure occures (add it to the zones and reconfigure you backup software).

Re: MSL2024 Zoning best practice
Unless I'm mistaken, each fibre port on this type of library provide dedicated data transfer for a single drive. There is thus no possibility of multipath failover. I'm not sure about how robot commands are handled.
Usually 'best practice' is to have a separate zone for each server FC-HBA and include in this zone the targets you want that server to see.
Note that the zones you have proposed don't allow the 'media server' to see the disk storage. Having a zone allowing the tape library and the disk storage to see each other doesn't accomplish anything, unless you are doing some type of 'active fabric'
backup (which nobody does, as far as I know).

Re: MSL2024 Zoning best practice
1) Backup software or OS support for dual path tape drives. HP-UX 11.31 and OVMS have OS level support for dual paths. Windows does not. Several backup apps on Windows support dual paths but I don't have an exhaustive list. Data Protector does not fully support dual paths yet.
2) If you don't have an OS or software that understands dual paths you can still plug both ports into your switch but put your failover port into an inactive zone so that the backup server only can connect to the primary port. If there is a link failure you can log into your switch remotely and switch the zoning to enable to failover port.

Re: MSL2024 Zoning best practice
Has anybody run some speed tests on these directly fibre connected drives on the non-overland MSL series? What is the top speed of these drives (espially LTO4) in this configuration? Thanks.
