Hi,

I do not understand the name change in LUN Assignments. What stands out to me are the odd balls.

What do they represent and used for?

Why are they skewed from the consistency of the others?

Page 37

Describes the LUN naming for V-series LUNs.

The name breaks down like this:

[switch name]:[port].[Device ID][LUN-id]

Example: BROCSANSW01A:4.126L63

Port 4 on switch:  BROCSANSW01A.  Device ID 126, LUN ID 63. 

The only difference I see in the LUNs you listed as oddballs is it lists them in the reverse order as the others.  Path 1 is normally switch B for your other LUNs, but it's Switch A for LUNs 63 and 64.  I don't think this is an issue and I'm not sure I'd worry about it.

Hi

Thanks exactly what I was trying to find. The Library is still down for Canada anyway. All the ducks are in line after I assign the LUNs and add to aggr.
