Answer

The following example shows how to find out which AIX hdisk is using which NetApp LUN. Here, we want to see which NetApp LUN is mapped to AIX hdisk6. AIX native commands are used to obtain more information since the customer has not installed the AIX Host utility kit.

AIX Server command:

This command will show the NetApp WWPN, AIX hdisk, NetApp LUN ID:

aix-cn22:/# lscfg |grep NetApp
* hdisk6           U0.1-P1-I6/Q1-W500A098196981B83-L5000000000000  MPIO NetApp FCP Default PCM Disk   ----> NETAPP WWPN and Lun id 5 (L5).
* hdisk7           U0.1-P1-I6/Q1-W500A098196981B83-L0              MPIO NetApp FCP Default PCM Disk   ----> NETAPP WWPN and Lun id 0 (L0).
* hdisk10          U0.1-P1-I6/Q1-W500A098196981B83-LF000000000000  MPIO NetApp FCP Default PCM Disk   ----> NETAPP WWPN and Lun id 15 (LF).
* hdisk11          U0.1-P1-I6/Q1-W500A098196981B83-LB000000000000  MPIO NetApp FCP Default PCM Disk   ----> NETAPP WWPN and Lun id 11 (LB).
* hdisk12          U0.1-P1-I6/Q1-W500A098196981B83-L1000000000000  MPIO NetApp FCP Default PCM Disk   ----> NETAPP WWPN and Lun id 1 (L1).
* hdisk2                                                           NetApp iSCSI LUN
* hdisk3                                                           NetApp iSCSI LUN
* hdisk9                                                           MPIO NetApp iSCSI Disk

This command will show what Fibre Channel (FC) adapter is installed on this AIX server:

aix-cn22:/ lsdev -C |grep FC
fcs0         Available 1V-08         FC Adapter
fcs1         Available 1n-08         FC Adapter
fscsi0       Available 1V-08-01      FC SCSI I/O Controller Protocol Device
fscsi1       Available 1n-08-02      FC SCSI I/O Controller Protocol Device
hdisk4       Defined   1V-08-01      MPIO NetApp FCP Default PCM Disk
hdisk5       Defined   1V-08-01      MPIO NetApp FCP Default PCM Disk
hdisk6       Available 1V-08-01      MPIO NetApp FCP Default PCM Disk
hdisk7       Available 1V-08-01      MPIO NetApp FCP Default PCM Disk
hdisk8       Defined   1n-08-02      MPIO NetApp FCP Default PCM Disk
hdisk10      Available 1V-08-01      MPIO NetApp FCP Default PCM Disk
hdisk11      Available 1V-08-01      MPIO NetApp FCP Default PCM Disk
hdisk12      Available 1V-08-01      MPIO NetApp FCP Default PCM Disk
hdisk14      Defined   1V-08-01      MPIO NetApp FCP Default PCM Disk

This command will show you the WWPN of the FC adapter:

aix-cn22:/# lscfg -vl fcs0
