[SAN-HPUX] How to find out the CLARiiON LUN number based on the HPUX host device output?

Firs t you will need to run ioscan -kfnC disk on the HPUX host, here is an output:

HPSRV01:/root<root> ioscan -kfnC disk

It's always confusing to read the ioscan outputs, in the output above:
disk     87  0/4/0/0.106.35.19.0.0.3   sdisk    CLAIMED     DEVICE       DGC     CX700WDR5
Here
0/4/0/0 = HBA
106= 96 + McDATA switch id
35= slot where Storage is attached (physical slot as labeled)
19 = McDATA
0.0.3 = 0*128 + 0*8 + 3 = LUN 33
So now we've identified C#T#D# corresponds to HLU number:

Next, Run the following command to display the Host LUN Number that corresponds to each Array LUN number:
[root(root)@HPSRV01/root]# navicli -h 192.168.100.50 storagegroup -list
Storage Group Name:    bl2c1u
Storage Group UID:     64:19:78:B4:AC:64:00:00:9D:FB:08:00:1B:43:9C:76
HBA/SP Pairs:
HBA UID                                          SP Name     SPPort
-------                                          -------     ------
50:06:00:00:00:25:AE:69:50:06:0B:00:00:25:AE:68   SP A         1
50:06:00:00:00:25:AE:69:50:06:0B:00:00:25:AE:68   SP A         0
50:06:00:00:00:11:9C:77:50:06:0B:00:00:11:9C:76   SP B         1
50:06:00:00:00:11:9C:77:50:06:0B:00:00:11:9C:76   SP B         0
HLU/ALU Pairs:

HLU Number     ALU Number
----------     ----------
0               0
1               15
2               29
3               31
Shareable:             YES

Now we can match ALU to HLU that we've identified earlier.
