Scenario for finding available LUNs

6.10 LPAR mode z/VM guest

There are several steps from setting an FCP device online to listing the available LUNs.

Procedure

Check for available FCP devices of type 1732/03:

# lscss -t 1732/03
Device   Subchan.  DevType CU Type Use  PIM PAM POM  CHPIDs
----------------------------------------------------------------------
0.0.3c02 0.0.0015  1732/03 1731/03      80  80  ff   36000000 00000000

Another possible type would be, for example, 1732/04.

Set the FCP device online:
```
# chccwdev 0.0.3c02 --online
```
A port scan is performed automatically when the FCP device is set online.

Optional: Confirm that the FCP device is available and online:

# lszfcp -b 0.0.3c02 -a
0.0.3c02 host0
Bus = "ccw"
    availability        = "good"
...
    failed              = "0"
...
    in_recovery         = "0"
...
    online              = "1"
...

Optional: List the available ports:

# lszfcp -P
0.0.3c02/0x50050763030bc562 rport-0:0-0
0.0.3c02/0x500507630310c562 rport-0:0-1
0.0.3c02/0x500507630040727b rport-0:0-10
0.0.3c02/0x500507630e060521 rport-0:0-11
...

Scan for available LUNs on FCP device 0.0.3c02, port 0x50050763030bc562:

# lsluns -c 0.0.3c02 -p 0x50050763030bc562
