Out-of-band management

Hi as long as you have IDRAC, SNMP won't be required nessrily. Wish you a good one.

I suppose you could argue that none of these components are required, necessarily.

So without SNMP installed on the servers, what provides OS-specific SNMP alerts?

My understanding is that ISM simply passes OS-specific SNMP alerts to iDRAC. Which means you would still need SNMP installed and configured on each host. Please correct me if this is wrong.

However, the question still remains; is ISM able to pass all the required OS driver information to OMEnt, or do we still need to install SSH?

Hello justin gray,

You can manage firmware of all the 'managed' devices that are discovered out-of-band using iDRAC.

You can update drivers of the 64-bit Windows-based servers that are discovered and managed in-band using the SSH protocol.

On the OpenManage Enterprise > Configuration > Firmware/Driver Compliance page, you can manage firmware of

all the 'managed' devices that are discovered out-of-band using iDRAC.

Additionally, you can update drivers of the 64-bit Windows-based servers that are discovered and managed in-band using the SSH protocol.

 To perform Windows driver update, ensure that the Windows servers are discovered in-band using the supported

protocol. To update both drivers and firmware, you must additionally discover the servers out-of-band using iDRAC.

Select Enable trap reception  to ensure that iDRAC SNMP alerts are being sent to, and received by, OME from discovered iDRAC Servers and MX7000 chassis.

This enables the OpenManage Enterprise to receive the incoming traps from the discovered Servers and MX7000 chassis.

@Dell -Charles R Thanks for the reply.

Can you clarify ISM driver component then? The language seems to indicate that it also provides driver capabilities: "The iDRAC Service Module architecture uses IP socket communication and provides additional systems management data (OS/device driver) to iDRAC..."

Hello justin gray,

This may give you the comparison you are looking for : In-band or out-of-band: Advantages of iDRAC and iSM compared to OMSA

Prior to OME3.2 you needed either iSM or OMSA installed in host to provide OS information to the DRAC.

In order to support discovery with domain credentials, OpenManage Enterprise (version 3.2 and later) uses the OpenSSH protocol instead of the WSMAN protocol used in the previous versions.

You will need to use SSH for Windows 64-bit driver updates.
