Updating EMM firmware

Steps

1. Download the latest firmware package from Dell.com/support.

2. Stop all I/O between the server and the attached enclosures containing the EMMs you intend to update.

NOTE:

• After this update process begins, you may lose access to the drives or enclosures connected to the update

target. The EMM does not respond to commands again until it is back online.

• If you have more than one storage enclosure in a daisy-chain, Dell EMC recommends that you update the EMMs

starting in the lowest tier of the chain and work back, up to the top enclosure.

3. Run the following command:

shmcli update emm -a=<(SASAddress | AdapterIndex)> -enc=<(WWN | EnclIndex)> -emm=<(WWN |

EMMIndex)> -file=<FW.FilePath>

NOTE:

The progress of the firmware transfer is indicated in the console.

4. EMM updates the firmware and restarts.

NOTE:

This process may take up to five minutes.

Identifying drives

When identifying drives, there are optional parameters that you can include to narrow the scope of the drives from which to obtain

information. You can identify drives from the adapter (all down-chain enclosures attached to a specified HBA), all the drives in a specific

enclosure, or all the drives in a specified drawer in a specified enclosure. To get information about all the drives visible to an adapter, run

the following commands:

To retrieve information about all of the drives on the server:

shmcli list drives

To retrieve information about all of the drives visible to an adapter:

shmcli list drives -a=<(SASAddress | AdapterIndex)>

For all the drives visible to an adapter:

To retrieve information about all of the drives in a specific enclosure:

shmcli list drives -a=<(SASAddress | AdapterIndex)> -enc=<(WWN | EnclIndex)>
