How can I see the mapping between the AIX hdisk and the NetApp LUN?
Applies to
- SAN
- FlexPod
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
aix-cn22:/#
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 give you the corresponding Lun serial number for the hdisk:
bash-4.4# lscfg -vl hdisk8
hdisk8 Other iSCSI Disk Drive
Manufacturer................NETAPP
Machine Type and Model......LUN C-Mode
ROS Level and ID............39353030
Serial Number...............80Ejn?Lq
Device Specific.(Z0)........0000043270181002
Device Specific.(Z1)........ZilO
Device Specific.(Z2)........S262
Device Specific.(Z3)........0
Device Specific.(Z4)........
Note: The Lun serial number has to be calculated by using the Serial number and Device Specific (Z1) i.e 80Ejn?LqZilO
This command will show you the WWPN of the FC adapter:
aix-cn22:/# lscfg -vl fcs0
fcs0 U0.1-P1-I6/Q1 FC Adapter
Part Number.................00P4295
EC Level....................A

Device Specific.(ZC)........00000000
Hardware Location Code......U0.1-P1-I6/Q1
