How to access and unmount Netapp FAS3140

DORAN_LUM — Thu, 05 Jun 2025 05:28:24 GMT

Hi all, I'm shutting down all my virtual environment in my data centre which leaves the storage as the last component to be shut down.

May i check if I could access the Netapp using SSH via the Mgmt port ?

I would be issuing the command to destroy all aggr but how do I also wipe out all configuration information ?

Anyone have experience in unmounting the Netapp storage ? Is it as easy as unplug all cables and just remove it from the rack ?

It depends on how thoroughly you want data to be wiped. The simplest approach is to boot in special boot menu and select 4 - this will zero all disks, assigned to controller, and create new configuration, similar to what you get from factory. Your old configuration data will be lost.

Sorry I manage to halt the system and then reboot it but encounter the below.

<1> MTL_MODULE(1): TAVOR_IF_CMD_STAT_DDR_MEM_ERR - memory error
<1> MTL_MODULE(1): THH_hob_create: CMD_error in THH_cmd_SYS_EN (7)
<1> MTL_MODULE(1): Please try powercycling the system. If the problem persists, please replace the motherboard.

I run boot_diags mb command and got the below.

NVRAM DDR memory error - you may have a bad NVRAM DIMM
THH_hob_create: CMD_error in THH_cmd_SYS_EN (7)
Please try powercycling the system. If the problem persists, please replace the motherboard.

Does this means the memory needs to be replaced ?
