EVA4400 - 2 libraries in the same SAN zone
Hava a SAN with 2 EVA4400 and three libraries.
With zones configured in host only to "see" EVAs I have no problems presenting new vdisks, but after adding the eight drives in the two libraries to the zone, presenting disk no longer working. Have too remove libraries from the zone, present disks and then readding libraries.
Need some guidelines in configuring zones for this environment. I want to remove backup traffic from the LAN and let hosts "see" the tape drives.
Using DataProtector 6 by te way.
Thank you
Regards

Re: EVA4400 - 2 libraries in the same SAN zone
A library's FC/SCSI converter should not be in the same zone of a disk storage array, because some of them go out into the FC fabric and log in to the disk array.

Re: EVA4400 - 2 libraries in the same SAN zone
It is always recommended to have Single Initiator Single Target.
For Libraries, do a Hardzone.

Re: EVA4400 - 2 libraries in the same SAN zone
Zone_Server1
(Server1_Port1,EVACTL1_Port1,EVACTL2_Port1,EVACTL1_Port2,EVACTL2_Port2)
Like this for every server (34 blades).
One zone for continuous access, with only EVA Controllers.
One zone for the backup server with the three librarys, two 8096 with 4 drives and one 2024 with one drive.
What I want to do is to send data directly form servers to tape drive, so following your recomendations, I should create one additional zone for every server inlcuiding the library ports and the service ports, right?
Will test it and let you know.
Thank you very much for your responses.

Re: EVA4400 - 2 libraries in the same SAN zone
Do CTRL1 and CRTL2 belong to the same EVA system? If not, you have created, what I call a 'leak' between two EVA systems. One day you might want to disable the communication between both systems by deactivating the CA-EVA zone(s), but replication will continue - due to the 'leaks'.
I really do bother and create two independent zones from a server to each EVA system. Yes, it is quite some work, but I avoid some 'surprises'.

Re: EVA4400 - 2 libraries in the same SAN zone
A MSL does not access a EVA directly. Typically, there's a server that accesses the disks on the EVA, and performs backup on the MSL. So you need a zone with server + MSL and another zone for server + EVA.
Also, it's recommeded to use a different HBA port for each zone.
