EML & e2400 NSR mapping

Hi Forum,
I have a EML Series
with 3 LTO

and we wanto to configure it in SAN... so:
we've created the ZONE on the FC-switch, and by serial-interface we're trying to configure the e2400 NS Router to present the host.

On "Fiber Channel Config". we change the default map value on FC Port0 anf FC Port1
we've tried to configure the map on Auto-Assigned and Index
and from the "Device Mapping" we tried to:
select map
edit the map (no for auto-assigned)
edit the host list for the map ( we have 4 host for the moment)
Activate and Saved the map.

we saved the configuration
abd then reboot.

but from my server, if I type ioscan -fn
I don't see any tape or Library

We're missing something???
do you have any suggestion?

thanks

Re: EML & e2400 NSR mapping

The "Port 0 Device" map is generally the one recommended for user reconfiguration. Add your hosts to that map and then add all the drives, the changer, and the NSR to the map.

Re: EML & e2400 NSR mapping

Hi..
I've rebooted the EML and I found the map "Port 0 Device" and "Port 1 Device".
I configured 2 host and that maps. but I don't see the 3 LTO. with ioscan I receive no_HW

this morning we tried to configure it to the index map... but we saw 6 LTO!! (duplicate)

Re: EML & e2400 NSR mapping

Configure both FC ports on NSR Bridges as follows when connected to a SAN:

Port Mode N_Port
Use Hard AL_PA No
Discovery Mode Manual Discovery Only (Default is Auto discovery)
Buffered Tape Writes Enabled, Queue Depth = 1
Default Map Indexed
Performance Mode 2 Gigabit

Re: EML & e2400 NSR mapping

The Active Fabric Device (AF) Lun0 should be seen under the following conditions :

Windows â Should be seen as the first device presented in the map.

HP-UX â Should be seen as the last device presented in the map.

Hi tkc,
I had configured the NSR as you described.

4 nsr " " 2

thanks.

Re: EML & e2400 NSR mapping

It may be that having your devices in two maps (Port 0 and Port 1) causes them two appear twice to your server. Make sure each device is only in one map or the other.

Re: EML & e2400 NSR mapping

in a eml library, you cannot change the maps in the NSR.
The library is a ETLA that's mean that there is an Interface manager that is working as a supervisor and managing the maps.
Now, what you want to do can be done from the CV-TL (Commmand View for Tape Library), once installed, you go under "Secure Manager" and here you can see all your hosts and set if they can see or not the library and drives (this is called presentation and mapping)
I read you want also to select wich port to use in the NSR for the specific device. In order to do that, you also need to by the license for Secure Manager. With the license, you can select drive by drive, the port you want to use, and if the drive shoud or not be presented to the single host.
