How to check Netapp Serial Number. The NetApp filer’s Serial Number (S/N) is stored in a file within the etc directory. You can use the rdfile /etc/serialnum/ command to display the Serial Number (S/N). In NetApp Data ONTAP GX, the file /mroot/etc/serialnum can be read to locate the Serial Number. In NetApp side iSCSI LUNs can be identified by Serial number, or LUN path, or even LUN id. But the same LUNs in ESXi can have the same LUN id, but you can have LUNs with the same LUN id from different systems. Besides that the LUNs in ESXi can only be identified by the identifier ID.
The serial numbers of the Filer (a.k.a. head) power supplies are not reported in the
environment status output. You can only retrieve it through physical inspection or using the
sysconfig -M command, depending on your Data ONTAP version and platform.
The serial number of each power supply is anyway located on top of the power supply Field Replaceable Unit (FRU). Unplug the power supply, remove the two thumbscrews and physically remove the power supply to view the serial number.
Filers that are in the FAS900 family or newer, and running ONTAP V 6.5.7 or higher, will show the serial number of the PSUs in the head in the
sysconfig -M output. However, older hardware and software platforms do not show the serial number of the PSUs in the head in the
sysconfig -M output.
Sysconfig -M example:
Filer> sysconfig -MCambridge ielts 6 listening test 1 mp3 free download full.
!System Serial Number!210283722!
!Chassis Power Supply!69815!856-851020!C1!
!Chassis Power Supply!69816!856-851020!C1!
In the example above, the serial numbers of the chassis power supplies will be the number between the second and third exclamation marks, so 69815 and 69816 respectively.
