[gpfsug-discuss] strange mmchnsd error?

[Bryan Banister]

ENODEV usually means that the disk device was not found on the server(s) in the server list.  In this case c100[5-8] do not apparently have access to r10f6e8,

I comment out the r10f6e8 line and then it completes?
I have some sort of fabric san issue:
[root at cl005 ~]# for i in {1..8}; do ssh cl00$i lsscsi -s | grep 38xx | grep 1.97 | wc -l; done
80
80
80
80
68
72

but i'm suprised removing one line allows it to complete.
