MD3000 Cluster Configuration Guidelines for
Standalone Host Servers
If one of the standalone host servers you are planning to configure into a
cluster environment is running MD Storage Manager and has a virtual disk
mapped to the array, use that host to create the Host Group and quorum
virtual disk mapping.
NOTE:
Failure to follow this mapping protocol can cause the host server to lose
communication with the array if the server is using only in-band management and
only one of the servers has a virtual disk mapped to the array. If communication is
lost, restore in-band management to the other host server and complete the cluster
setup using the following procedure.
1 Using MD Storage Manager from either the host server with restored in-
band management or from a management station, select Configure
→
Create Host-to-Virtual Disk Mappings.
2 Select the host server name that does not have a virtual disk mapped.
3 Click Access to access the virtual disk.
4 Assign a logical unit number (LUN) of 31.
5 Click Finish.
