Description

This script performs a variety of checks against an ONTAP SAN based system and returns the results in an Excel spreadsheet.  Following are the checks involved.

Script Detail
  1. Compare the initiators defined in each igroup against the actual logged in initiators on each node.
  2. Show total number of initiators per LIF (beneficial for Calculating queue depth).
  3. Gather FCP adapter details that might have a best practice impact.
  4. Compare selective LUN mapping reporting-nodes against the hosting HA pair, other nodes in the cluster, and nodes no longer in the cluster.
Example Output
FCP Initiators
Igroup Initiator Alias LIFs Portsets Nodes Found Nodes Missing Status
IGROUP1 50:01:01:01:01:01:01:01   fclif01_2a,fclif02_2a HostGroup01 CLUSTER1-01,CLUSTER1-02   CORRECT
IGROUP2 10:00:00:00:00:00:00:00   fclif01_0e HostGroup05 CLUSTER1-01 CLUSTER1-02 INCOMPLETE

 

LIF Counts
LIF Number of Connected Initiators
fclif01_0e 44
