Multi-Path setup for VMware

Multipathing enables you to configure multiple I/O paths between server nodes and storage arrays into a single device. These I/O paths are physical SAN connections that can include separate cables, switches, and controllers.

The following instructions are provided for the administrator of the DE Series storage array to set up multi-path for VMWare.

After the installation, manually create claim rule with the following command. Then restart the client machine:
esxcli storage nmp satp rule add -s VMW_SATP_ALUA -V LENOVO -M 
DE_Series -c tpgs_on -P VMW_PSP_RR -e "Lenovo DE-Series arrays with ALUA support"

For iSCSI SANboot, ensure any vmkernel that participates in SANboot has a MAC address that matches the physical adapter. The default adapter created during the installation will match by default.

Use the following command to create additional vmkernel to specify the MAC address:
esxcli network ip interface add -i [vmkernel name] -M "[MAC address]" -p "[Portgroup name]" -m [MTUSIZE]
