Dell EMC VXRAIL useful tips & trics

VXRAIL Manager election:
During powerup the vxrail manager vm will start on one of the nodes.
To find out which host is running the VM:
– connect to the DCUI (login with root Passw0rd !)
– enable ESXi shell
– ALT-F1 to open ESXi shell
– run following commands:
#vim-cmd vmsvc/getallvms
#vim-cmd vmsvc/power.get 1
– ALT-F2 to exit ESXi shell

How to find the installed VXRAIL code on the ESXi host:
#esxcli software vib list | grep marvin

How to change the primary IP of the VXRAIL manager VM:
#vxrail-primary –setup –vxrail-address 192.1.20.50 –vxrail-netmask 255.255.255.0 –vxrail-gateway 192.1.20.1 –no-roll-back –verbose
#vim-cmd vmsvc/getallvms (find the ID of the vm)
#vim-cmd vmsvc/power.get 1
#vim-cmd vmsvc/power.off 1
#vim-cmd vmsvc/power.on 1

How to change VLAN settings
#esxcli network vswitch standard portgroup list
#esxcli network vswitch standard portgroup set -p “VM Network” -v 120

Some esxcli commands
ESXi build: #esxcli system version get
Hostname: #esxcli system hostname get

enter Maintenance Mode: #esxcli system maintenanceMode set –-enable true
exit Maintenance Mode: #esxcli system maintenanceMode set –enable false
Status Maintenance Mod: #esxcli system MaintenanceMode get

Shutdown ESXi (first set maintenance mode): #esxcli system shutdown reboot -d 20 -r “Test reboot”
IPv4 Config of all interfaces: #esxcli network ip interface ipv4 get
Command list: #esxcli esxcli command list

VNX DPE / DAE SAS cabling

A quick note to clarify SAS cabling between EMC VNX and extra enclosures or DAE’s as they are called.

When setting up a VNX with only the base DPE enclosure, there’s no need for cabling.

When adding the first and the second enclosure, you need a special kind of SAS cable, called the “mini-SAS to mini-SAS HD cables”.

When adding a third enclosure or more, you need a “mini-SAS to mini-SAS cable”.

The following is an overview on the partnumbers for both situations:VNXSAS
