and their ports, WWNs, nicknames, and LDEVs for later use in verifying host and
device configuration.

Verifying host recognition of disk array devices

To verify that the host recognizes the disk array devices:

1.
Log into the host as an administrator (root).
2.
If the disk array LUNs are defined after the IBM system is powered on, issue a
cfgmgr command to recognize the new devices.
3. Use the lsdev command to display system device data and verify that the system
recognizes the newly installed devices.
The devices are listed by device file name. All new devices should be listed as
"Available." If they are listed as "Define," you must do more configuration before
they can be used.
Example
The example shows that Device hdisk0 is installed on bus 60 and has TID=5 and
LUN=0.
4.
Record the device file names for the new devices. You will use this information in
changing the device parameters.
5.
Use the lscfg command to find out the AIX disk device's corresponding array LDEV
designation.
Example
In this example, the emulation type, LDEV number, CU number and array port
designation should all be displayed for disk device hdisk3.
