Article Content


Symptoms
The iDRAC display of System Hostname or System Operating Systems is not populated or does not match the system information.
Cause
iDRAC does not poll the hostname of the Operating System.
Resolution

The recommendation is to install the Dell EMC iSM (iDRAC Service Module) or OpenManage Server Administrator vSphere Installation Bundle (VIB) for ESXi in the ESXi operating system.


Alternately, use the following IPMI raw commend to update the iDRAC hostname.
The hostname is visible in iDRAC WEBGUI after refreshing the page. In order for the hostname to refreshed in CMC, the iDRAC will need to be reset.
Command Details:

raw 0x06 0x58 0x02 0x00 0x05 0x04 0x4c 0x4d 0x4e 0x4f

Byte 0 : 0x06 Network Function
Byte 1 : 0x58 Command
Byte 2 : 0x02 Parameter Selector (distinguish between set Firmware Version, OS Name, System Name etc.)
Byte 3 : 0x00 Set Selector (this equals 0 implies that the user is setting the parameter)
Byte 4 : 0x05 Check String data
Byte 5 : 0x04  --> data length
Byte 6…n : data bytes

Usage:

For example, to set the hostname to DELL

raw 0x06 0x58 0x02 0x00 0x05 --This part is common
0x04 -- hostname string length- four characters(DELL) in our example
0x44 0x45 0x4c 0x4c -- ASCII equivalent for DELL
It is advised to use a ASCII to Hex convertor with the prefix 0x to easily translate the characters.
