Managing ESX servers
Using the following procedures, you can modify parameters on ESX servers and check
the SDC state on ESX servers.
Modifying parameters on ESXi servers
About this task
On an SDC running on an ESXi server, esxcli commands can be used in the following
cases:
l
MDM IP addresses need to be added to the existing list on an SDC
l
MDM IP addresses need to be replaced on an SDC
l
The SDC’s GUID needs to be changed
Specifically, the SDC’s GUID or IP address needs to be identified, and then used to
add or modify the MDM IP addresses or GUID (depending on the parameter that you
want to modify). If you want to add additional MDM IP addresses to existing ones, you
must list both old and additional IP addresses in the esxcli command.
For more information about SDC tuning, see "VxFlex OS performance fine-tuning".
Note:
These procedures require a server restart to apply the new configuration.
The configuration will remain persistent after future server restarts.
To configure MDM IP addresses on the SDC, perform these steps:
Procedure
1. Find the SDC’s GUID and the MDM IP addresses configured on the ESX, by
typing the command:
esxcli system module parameters list -m scini
2. In the output of the command, find the existing GUID and MDM IP addresses.
