In order to interact with the RAID controller on a Cloudvue Gateway you must first install storcli.

Cloudvue Gateway with RAID Controllers
Steps
Verification
Confirm RAID Controller Present
Use lshw to determine if a RAID Controller is present. If no results are returned then there is no RAID controller detected, thus no reason to proceed.
sudo lshw | grep -i RAID
Verify storcli is Not Installed
The following commands can be used to determine if storcli has already been installed.
which storcli sudo find / -name storcli
Install storcli
Prep and Download Package
Update Ubunutu and download storcli
sudo apt update mkdir Downloads cd Downloads/ wget https://docs.broadcom.com/docs-and-downloads/raid-controllers/raid-controllers-common-files/1.23.02_StorCLI.zip
Install unzip
Install unzip and unzip storcli
sudo apt install unzip unzip 1.23.02_StorCLI.zip unzip storcli_All_OS.zip cd storcli_All_OS/
Install Alien and storcli
Alien is a command line package converter. It is used to convert the storcli rpm package downloaded earlier to a deb package allowing us to install storcli using dpkg.
sudo apt install alien cd Linux sudo alien --scripts storcli-1.23.02-1.noarch.rpm sudo dpkg -i storcli_1.23.02-2_all.deb
Setup Symbolic Link
For ease of use find the storcli install and then create symbolic linking allowing the storcli to be launched from any folder.

LSI Storage Authority (LSA)
Steps to Reproduce
Launch LSA from the desktop
Enter the administrators username and password
Expected Results
Login is successful and the LSI Storage Authority Landing Page is displayed
Actual Results
Login fails with Error Code 49: Invalid Credentials
Solution
LSA fully supports English OS only.If you are using native German, French or Spanish OS, you need to edit the LSA.conf file and translate “Administrators” to your native language. Resolve Error Code 49: Invalid Credentials with the following steps:
Expanding a MegaRAID Virtual Drives Capacity using LSA – Empty Slots Available
Description
Expanding a virtual drive means increasing its capacity. Existing data on the virtual drive is not impacted by the expansion. Follow these instructions to add a physical drive and expand the virtual disk size using LSI Storage Authority. Expanding a RAID volume by adding hard drives is only available with RAID 0, 1, 5, and 6 configurations. RAID volume expansion will not work with other RAID configurations, such as RAID 00, 10, 50, or 60.
NOTE: Capacity expansion is only possible on RAID 0, 1, 5 and 6. Please keep in mind, there should only be “1 virtual drive” on the array. If you have more than 1 virtual drive, then you cannot enlarge your array. You will have to create a backup, delete the array, create a new RAID, and restore your backup to the new virtual drive.
Caution: Physical drives with the same or larger capacity as the existing drives should be used. If the new drive has a larger capacity only the amount matching the current physical drives making up the Virtual drive will be used. For example, if the existing Virtual Drive consist of 4TB drives and a new 6TB drive is used to expand the Virtual Drive, the capacity of the new drive will be reported at 4TB, and the virtual drive will only be increased by 4TB.

Overview
Add Physical Drives
Check current drive group and virtual drive configuration
Modify Drive Group
Expand existing partition in the operating system
Verify virtual drive is present, healthy and operational
Add Physcial Drives
Note: Drives are hot swappable so it is not necessary to shutdown or restart the server
Remove an empty drive tray
Place the new physical drive in the tray and use screws to secure it to the tray
Align the drive tray into the slot and gently slide into position using a final levering action to latch the drive in place.
You will feel some resistance just before the drive seats itself into the backplane and the lever arm locks in place. DO NOT FORCE THE DRIVE INTO POSISTION.
A White LED should be visible once the physical drive has been correctly seated
Check Current Drive Group and Virtual Drive Configuration
Launch LSA from the desktop
Enter the operating systems administrators username and password
Use the drop down to Select Controller, the controller dashboard will appear
Physical Drives Tab
Ensure that all Physical Drives are present and have a status of Unconfigured Good
If not, please refer to the following Knowledge Base Article(s) for additional information.

Perform the following steps to import or clear foreign configurations.
Navigate to the Controller dashboard.
Click Configure and then click Foreign Configuration.
The Foreign Configuration window appears, which lists all of the foreign configurations.
Click one of the following options:
• Import All: Import the foreign configurations from all the foreign drives.
• Clear All: Remove the configurations from all the foreign drives.
All physical drives connected to the MegaRAID controller can be managed using LSI Storage Authority.

Erasing a Drive
You can erase data on non-SEDs (normal HDDs) by using the Drive Erase option. For non-SEDs, the erase operation consists of a series of write operations to a drive that overwrites every user-accessible sector of the drive with specified patterns. It can be repeated in multiple passes using different data patterns for enhanced security. The erase operation is performed as a background task. Perform the following steps to erase a drive.
Navigate to the Controller dashboard, and click the Drives tab.
All of the associated drives appear.
Expand Unconfigured Drives and select an unconfigured good drive.
Select Element(s) Actions > More Actions > Drive Erase.
The Physical Drive Erase dialog appears.
The dialog shows the following modes:
• Simple
• Normal
• Thorough
Select a mode, and click Erase Physical Drive.
A warning message appears asking for your confirmation.
Click Yes, Erase Drive.
After the drive erase operation has started, the Stop Erase option is enabled in the Element(s) Actions menu. You can monitor the progress of the erase operation.

Meaning of the UBAD or UGOOD messages, most commonly seen in RAID Controller, but may appear in Storage.
Product
exacqVision Server
Information
UGOOD (Unconfigured Good)
This means a drive has been found that does not have a RAID configuration, but was not automatically imported into the RAID as a replacement drive.<br><br>
UBAD (Unconfigured Bad)
A drive may enter this state if it was unexpectedly powered off or disconnected. The drive should be re-seated and imported back into the array.
If the problem returns, the drive should be swapped with another drive, then follow the problem to diagnose.<br><br>
Solution
If the same disk, moved to another slot, goes back to the UBAD status, the disk itself is bad. Replace the drive.
If the previously good drive, moved into the same slot, goes into a UBAD state, the backplane or cabling may be the problem. Check the cabling. If the cabling looks okay and is seated properly, RMA/Repair the machine.
Meaning of Foreign Configuration message from RAID
Product
ExacqVision Server
Information
Each drive in RAID Controller’s configuration has a bit of information about the controller it is on written to it. Sometimes, a RAID Controller will detect that information about a controller exists on one or more of the drives, but it does not match what the controller expects.
Solution
If the customer has moved hard disks from one machine to another:
If the customer does not need the data from the newly inserted drives, the Foreign Configuration can be cleared, and the newly added drives can be imported into the RAID.
If the RAID Controller has been replaced:
The Foreign Configuration should be imported from the Drives into the RAID Controller.
