Step 2 Choose a configuration type:. Caution If you choose Clear Configuration or New Configuration , all existing data in the configuration is deleted. Back up data that you want to keep before you choose a configuration type.
The following number of drives is required: New RAID 5 virtual drives must have at least five drives for a background initialization to start. New RAID 6 virtual drives must have at least seven drives for a background initialization to start.
We recommend that you use either a battery to protect the controller cache or an uninterruptable power supply UPS to protect the entire system.
If you do not use a battery or a UPS, and there is a power failure, you risk losing the data in the controller cache. Caution LSI allows Writeback mode to be used with or without a battery. LSI recommends that you use either a battery to protect the controller cache or an uninterruptable power supply UPS to protect the entire system. Policies area—Lists the virtual drive policies that were defined when the storage configuration was created.

This window contains the following information: Battery information Design information Capacity information Auto Learn properties and settings Most of the Battery Module properties are view-only and are self-explanatory. Managing RAID This section includes information about maintaining and managing storage configurations. Expanding a Virtual Drive You can increase the size of a virtual drive to occupy the remaining capacity in a drive group. Monitoring Array Health You should periodically run a consistency check on fault-tolerant virtual drives.
The consistency check begins. Recovery MegaRAID Recovery, also known as Snapshot, offers a simplified way to recover data and provides automatic protection for the boot volume. Caution Do not select the virtual drive containing the operating system OS as the Snapshot Repository. Updates to the operating system or operating system crashes could destroy data on that virtual drive. Deleting a Virtual Drive You can delete any virtual drive on the controller if you want to reuse that space for a new virtual drive.
Caution Back up any data that you want to keep before you delete the virtual drive. Migrating an Array to a New Server A foreign configuration is a storage configuration that already exists on a set of drives that you install in a server.
Foreign Configurations in Cable Pull and Drive Removal Scenarios If one or more drives are removed from a configuration, for example, by a cable pull or drive removal, the configuration on those drives is considered a foreign configuration by the RAID controller. Original Number of Drives in the Drive Group. Caution Back up any data that you want to keep before you change the RAID level of the virtual drive.
If you do not have a record of which option is used in your server, you can read the on-screen messages that are displayed during system bootup Information about the card models installed are displayed as part of the verbose boot. Step 5 Press F when you see the following on-screen message: Foreign configuration s found on adapter. All of the disks from your previous configuration are gone. If this is. N Virtual Drive s found on host adapter.
Limitation on Importing Foreign Configuration To a Virtual Disk That is Under Construction Limitation When the reconstruction operation of a virtual disk VD is in progress and the controller fails or the VD changes to an offline state, you cannot import the foreign configuration and the VD cannot be recovered. The limitations of this design are as follows. The RLM operation cannot be aborted once started. If all of the VDs that are undergoing the RLM operation change their state to offline drives are pulled out or the enclosure powers off and then if drives return, the VD is foreign and in offline state.
Then the VD enters into the morphing state. Prerequisites For Reconstruction to Start Firmware performs checks before starting the reconstruction operation on a VD. It fails the reconstruction command if any of the following conditions exist: Reconstruction is already active multiple reconstructions are not allowed.
Rebuild operation is active. Copyback operation is active. Check Consistency is active. Background Initialization is active. Virtual drive initialization is active. Both have been plugged in for a couple of days so it should have had pleanty of time to charge. ETA 3 to 6 Weeks.
