OnCommand Insight Device Resolution: Part 1 of 2

1) What is OCI’s device resolution?

Resolving or identifying devices in your environment that have not been identified through data sources.
For example: Physical Hosts, Storage Arrays, Tapes, Switches

2) Why should I identify devices?

Necessary to accurately track performance and inventory data in your environment.

3) What’s my identified device coverage look like today?

Start with reviewing “FC Identify” and “IP Identify” tabs.

Ideally want to see > 90% FC/IP identifed in production environments.

4) Methods for identifying/resolving devices

FC Identify (FC Device):
- Auto resolution rules
--- Can identify hosts or tape
--- Uses Regular Expressions or Delimeters to extract device name from aliases
--- Best method for automating FC device discovery
- Manual Identification
--- Can be used to identify hosts, storage, or tape
- CSV Import

IP Identify (iSCSI/NAS Device):
- Auto resolution of IPs
--- Enables automatic resolution for iSCSI initiators and hosts accessing NFS shares
--- Uses DNS lookup
- Manual Identification
- CSV Import

Note: Auto-resolution is not going to be able to identify devices connecting in through CIFS shares.

Creating Host Resolution Rules: FC Identify
- Goal: Extract device names from aliases
- What’s needed:
--- Type of devices you are identifying (each rule is specific to Hosts or Tape)
--- Alias that you are extracting host/tape from (SRM/Storage/Switch/Zone alias)
- Method of extraction:
--- Regular expressions (recommended)
--- Delimiters
--- As is (SRM Alias only)

Auto Resolution of IPs
Tick the ‘Auto resolution of IPs’ box (make sure to add domains for DNS lookup)!
