An example is displayed below how to enable and disable a LED. The LED status of the drives can also be controlled by the ssacli utility. This can be interesting for when you add new drives in hot swap bays. To issue a controller rescan, you can run the following command. ssacli ctrl slot=1 ld 2 modify size=max forced # Modify - Extend logical drive 2 size to maximum (must be run with the 'forced' flag) ssacli ctrl slot=1 ld 1 add drives=allunassigned # Add - All unassigned drives to logical drive 1 Keep in mind: make a backup before performing the procedure. You need to perform two actions: adding the drive(s) and expanding the logical drive. HPE SSACLI вЂ“ Adding drives to logical driveДЄdding drives to an already created logical drive is possible with the following commands. ssacli ctrl slot=1 create type=ld drives=1I:0:1,1I:0:2 raid=1 forced ssacli ctrl slot=1 array all add spares=2I:1:6,2I:1:7 ssacli ctrl slot=1 create type=ld drives=2I:0:8 raid=0 forced # Show - Controller slot 1 logical drive 1 statusД¬reating a new logical drive can be done online with the HPE Smart Array controllers.

# Show - Controller Slot 1 full configuration # Show - Controller Slot 1 Controller configuration detailed # Show - Controller Slot 1 Controller configuration basic The extensive detail is very useful for troubleshooting and gathering information about the system. To view the status of the controller, disks or volumes you can run all sorts of commands to get information about what is going on in your VMware ESXi server. Drives that are unassigned: allunassigned A range of drives (one to three): 1E:1:1-1E:1:3 The give you an idea what valuable information can be shown.ДЄll commands have a short name to reduce the length of the total input provided to the ssacli tool: # Shortnames: Screenshots were taken by doing maintenance on VMware ESXi servers. I have collected some screenshots over the years.

Here is a list of locations that have been used for the last ten years for VMware ESXi: # Location VMware ESXi 4.0/4.1/5.0 Over the years the name of the HPE Storage Controller Tool has been changed and so has the location.

This means it can also be updated with vSphere Update Manager. The tool is installed as a VIB (vSphere Installable Bundle). The tool is already pre-installed when installing ESXi. In case you are using the HPE VMware ESXi custom images. Here is an overview of supported controllers: The tool supports the most HPE SmartArray controllers over the last 10 to 15 years, for example, the Smart Array P400 was released in 2005 and is still working fine today.

It was already available for VMware ESX 4.0 and is still available in VMware ESXi 6.7. So far as I can remember it has been there for ages. The main difference has always been that the HPE tool can perform the operation live without downtime. So far as I know I havenвЂ™t seen an identical tool yet from the other server hardware vendors like Cisco, Dell EMC, IBM, and Supermicro. The tooling of HPE is very powerful because you can online manage a VMware ESXi host and migrate for example from a RAID 1 volume to a RAID 10 without downtime or change the read and write cache ratio. This time I decided to do a blog post about the HPE Smart Array RAID controllers with their wonderful ssacli tool.
