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)!
