Modular Disk Storage Manager
The following updates apply to the Modular Disk Storage Manager (MD Storage Manager):
• The MD Storage Manager graphical user interface (GUI) lists RAID 3 as an option for virtual disks.
This option is not supported for this product. If the RAID 3 option is selected, the MD3000 system
creates a RAID 5 RAID group. The level of this RAID group is erroneously reported as RAID 3.
The RAID 3 option will be removed in a subsequent release.
• When the MD Storage Manager is being installed on Red Hat
®
SUSE Linux Enterprise Servers, or when the MD Storage Manager is run under SUSE Linux
Enterprise Servers, Japanese and Simplified Chinese are not supported.
Password Resets
If a password reset is ever required, refer to the password reset procedure for the Dell PowerVault
MD3000 Storage Enclosure at support.dell.com. If you require help with this procedure, contact Dell
for technical assistance. For more information on contacting Dell, see the "Getting Help" chapter of
the Hardware Owner's Manual.
MPP Failover Driver Loading
For users running Red Hat Enterprise Linux version 3.0 (x86), the mpp_vhba failover driver component
does not load unless a storage array is connected and a LUN is mapped to the host server.
Follow these steps to ensure proper MPP driver loading and LUN mapping:
1 Ensure that the storage array is connected to the host server and that all installation instructions have
been completed, including the connection of the out-of-band (Ethernet) connections to each RAID
controller module.
2 Create a virtual disk and map it to LUN 0.
3 Reboot the host.
After the host is rebooted, the LUN is properly mapped and the MPP driver is loaded. Subsequently,
all other sequential LUNs can be created and registered to the OS by running hot_add.
