MD3000 Configuration Considerations
When configuring the MD3000, consider the following updates.
Changing Controller Ownership of the Virtual Disk
For hosts that have a single data path to the MD3000 storage array, the virtual disk must be owned by the
controller to which the host is connected. Configure this storage array before starting I/O operations.
To assign ownership of the virtual disk to the connected controller, select Modify→ Change Virtual Disk
Ownership/Preferred Path from the MD Storage Manager GUI after the virtual disk is created.
Advanced Configuration Considerations
Some configuration options are best explored with the aid of Dell technical assistance. In particular,
the Advanced option of the MD Storage Manager's Tools→ Change Network Configuration GUI
should only be used with the guidance of Dell technical assistance.
Command Line Interface Updates
Users of the command line interface should note the following information:
1 The diagnose controller command's testID parameter takes the following options:
• 1 — Reads the test
• 2 — Performs a data loop back test
• 3 — Writes the test
2 If configuration of the MD3000 storage array is cleared using the clear storagearray configuration
command, restart all attached hosts prior to reconfiguring the storage array.
3 When using the command-line interface to create host ports, ensure that the host type is specified in
the command. If no host is specified, the default host is Windows 2000/Server 20003 Non-Clustered.
4 The SMcli -d parameter shows all storage arrays that are currently discovered.
SAS Connections
OpenManage software users who want to install a SAS 5/E connected to an MD3000 storage array must
first download and install the OM5.1.0.1 patch from the Dell Support website at support.dell.com.
This is a prerequisite in order for the OpenManage software to function properly.
A SAS Device Miswire Recovery Guru condition can be generated by connecting the host port of one
controller to the unused expansion port on the other controller in a MD3000 enclosure. This miswire
was not specified in the recovery procedures included with the MD3000 documentation.
