MegaRAID Storage Manager (MSM) Installation |
Note - MegaRAID Storage Manager (MSM) is also known as MegaRAID Storage Manager - Integrated RAID (MSM-IR) for versions earlier than 2.x. Some x64 servers support MSM 2.x; others support MSM 1.x versions. |
Note - The MSM installation files and drivers were installed on your system if you selected the correct optional components during the Windows 2003 Server installation. If you did not select these components, continue with this procedure. |
To Install MSM on the Windows OS |
To Install MSM on the Linux OS |
# lsmod | grep mptctl |
To Create a Partition and Filesystem on Linux OS |
Note - You can create a partition that is smaller than the maximum size of the device or create multiple partitions on the device. See the fdisk man page for details. |
Note - You can create a number of different types of file systems under Linux. This section covers a default configuration of ext2 and ext3 file systems. Refer to the documentation included with the file system of your choice for complete instructions. |

Using MegaRAID Storage Manager |
Note - MegaRAID Storage Manager (MSM) is also known as MegaRAID Storage Manager - Integrated RAID (MSM-IR) for versions earlier than 2.x. Some x64 servers ship MSM 2.x; others support MSM 1.x versions. |
To Start MSM on the Windows 2003 Server |
Tip - Alternatively, double click the MSM icon on the desktop. |
To Start MSM on a RHEL 4 Server |
To Start MSM on a SLES 10 Server |
Note - If a warning appears indicating the Windows Firewall has blocked some features of the program, click Unblock to allow MSM to start. The Windows Firewall might block some Java based programs like MSM. If there are multiple servers on the network, you might experience a delay before the Select Server window appears. A network with multiple servers might look similar to the Select Server window shown in FIGURE 8-1. |
Note - You can access servers on a different subnet by entering an IP address in the Connect to remote Framework at field at the bottom of the screen. The check box next to the Connect to remote Framework at field enables you to access a standalone server running MSM, if it has a network connection. |
To Access Servers on Alternate Subnets |
To Log in to MSM |
Note - If you are accessing the server over a network, you will also need to enter the root/administrator user name and password to use Full Access mode. Step 4 gives you access to the server, but not full access over the network. |
System | Degraded state -- A yellow LED indicates that the device is running in a degraded state. For example, the yellow LED next to virtual disk indicates that it is running in a degraded state because a disk drive has failed. |
Controller | |
Port | |
Disk group | Device failure -- A red LED indicates that the device has failed. For example, the red LED next to disk drive icon indicates that it has failed. |
Virtual disk | |
Physical disk drive |
Note - Some events in MSM_IR do not display an accurate date and timestamp value in the MSM log. When this is the case, the date and timestamp line will display '#####' as the value. For example, creating a new RAID 0 or RAID 1 will generate '#####' in the MSM date & timestamp log. Also, swapping hard disks will only display '###################' in the MSM log section. |
Note - You can view the Redundant Paths property when you remove and restore a path to verify that your version of MSM is multi-path aware. |
Note - When you use MSM online Help, you might see a warning message that Internet Explorer has restricted the file from showing active content. If this warning displays, click the active content warning bar and enable the active content. |
Note - Physical disk drives with bootable partitions cannot be used to create a virtual drive on a SAS IR controller with MSM. Drives with bootable partitions do not appear on the list of available drives to create a new virtual drive. To make physical disk drives with bootable partitions available for use in creating a virtual drive, you must clear the bootable flag in the partition or remove the partition. |
To Start the MSM RAID Configuration Wizard |
Note - Two disks can be selected at the same time by using the shift key after making the first disk drive selection. |

Note - MSM might also be installed from the BIOS. For details see the Service Manual for your product. |
Caution - To prevent an inoperable system, do not initialize a drive on which the operating system is installed. Initializing any drive overwrites the drive contents, including the operating system if it is installed. |
Note - Support is provided for enabling/disabling SMART and Write Cache Enable on physical disks that are not part of a virtual disk, but are connected to a SAS IR controller. This is different from the way in which properties are changed for virtual disks. |
To Change a Virtual Disk Property |
Caution - To prevent any data loss, including the operating system (OS), back up the data on the virtual disk before you delete it. Ensure the operating system is not installed on the virtual disk you intend to delete. |
Note - Virtual drives with a bootable partition cannot be deleted. This prevents you from accidentally deleting a drive that contains the operating system. To delete the virtual drive, you must clear the bootable flag in the partition or remove the partition. |
To Delete A Virtual Disk |
Caution - This SaveConfigurationcommand is problematical and is not supported. |
Caution - To prevent any data loss, back up the data on the virtual disk connected to the controller before you clear a configuration. Clearing a configuration deletes all data from the disks of the existing configuration. |
To Clear a Configuration from a Controller |
Note - Some events in MSM_IR do not display an accurate date and timestamp value in the MSM log. When this is the case, the date and timestamp line will display '#####' as the value. For example, creating a new RAID 0 or RAID 1 will generate '#####' in the MSM date & timestamp log. Also, swapping hard disks will only display '###################' in the MSM log section. |

To Rebuild a Drive on a SAS IR System |
Note - The option to mark a physical disk (drive) as missing does not appear in some versions of MSM. In those versions where “Mark physical disk as missing” is disabled or not available, you will see 'Mark drive online' and 'Rebuild' options. |
Note - If a disk drive in a virtual disk has failed, the drive goes offline. If this happens, you must remove the disk drive and replace it. You cannot make the drive usable for another configuration by using the Mark physical disk as missing and Rescan commands. |
