The IBM Systems Storage 8000 and IBM ESS800 systems use an active-active array that does not need special configuration in conjunction with VMware ESXi.
The following considerations apply when you use these systems:
- Automatic resignaturing is not supported for these systems.
- To use RDMs successfully, a given LUN must be presented with the same LUN ID to every ESXi host in the cluster.
- In the ESS800 Configuration Management tool, select Use same ID for LUN in source and target.
- If you are configuring the host to use boot from SAN from these arrays, disable the internal fibre port for the corresponding blade until installation is finished.
