The iDrac can't be reached after selecting shared NIC

Hello,

I changed the NIC Selection Mode of my M620 server (slot 2) from Dedicated to Shared, and now I can't access iDRAC via a web browser.

I don’t have physical access to the servers, and I need help with the following:

A) Is it possible to revert the NIC back to Dedicated remotely, without physical access?

B) If not, how should I configure my switch to regain access to the server’s management IP via the web?

Currently, I can't even ping the server. However, all other servers, I/O modules, and the chassis management IP (iDRAC) are reachable.

Thanks for your help!

Hi,

 

Answer to B, I don't think you can do configuration to the switch to gain access to the iDRAC Shared LOM. I've tried to check in our test units, though I don't have full admin access to the chassis CMC, I can't be 100% say there isn't a setting that you can configure the M620's iDRAC interface selection. I can only find IP address configuration. So, the only way I can think of, is to try use RACADM on the chassis CMC. Here's the RACADM CLI user guide: https://dell.to/3WKb4o6

 

Can you try racadm getniccfg [-m ] to check if you are able to pull the information of the iDRAC. If yes, try:

 

racadm -r <CMC_IP> -u <username> -p <password> -m server-1 set iDRAC.NIC.Selection 1 ; in which of the server slot resides, server-N obtained from racadm getmodinfo

@DELL-Joey C​  thank you for your reply. 


I run racadm remotely and the output of "racadm <-r with credential> -m server-n getniccfg" 

Here is the output:

LOM Model Name            = Intel(R) 10G 2P X520-k bNDC
LOM Fabric Type           = 10 GbE KR
IPv4 Enabled              = 1
DHCP Enabled              = 0
IP Address                = 10.12.100.1
Subnet Mask               = 255.255.0.0
Gateway                   = 10.12.1.254
IPv6 Enabled              = 0
Autoconfiguration Enabled = 0
Link local Address        =
IPv6 Gateway              = ::
VLAN Enable               = 0
VLAN ID                   = 1
VLAN priority             = 0

Running "racadm -r <CMC_IP> -u <username> -p <password> -m server-1 set iDRAC.NIC.Selection 1" 

I get:  Invalid option -m specified
