Preparing and Installing Auxiliary Tools and Software

Before expanding the capacity of storage systems, prepare and install auxiliary tools and software to ensure smooth capacity expansion.

Table 4-1 lists the auxiliary tools required for capacity expansion.

Table 4-1 Auxiliary tools required for capacity expansion

Tool	Used To
Serial cable	Log in to the serial port of a storage system.
(Optional) USB-to-serial adapter cable	Connect to a storage system. If the maintenance terminal is a laptop without a serial port, use the USB-to-serial adapter cable to connect to the storage system.
Cable tie	Bundle new cables.
Label	Mark the position of a cable before it is removed, preventing the cable from being inserted into a wrong slot during capacity expansion.
Marker	Mark locations and scales.
Diagonal pliers	Install ground cables.
Phillips screwdriver (M3 to M6)	Fasten small screws and bolts.
(Optional) Flat-head screwdriver (M3 to M6)	Replace the floating nut mounting bar, install and remove floating nuts.
Floating nut mounting bar	Install and remove floating nuts.
Installation template	Determine installation positions.
ESD clothes	Protect from electrostatic discharge.
ESD gloves	Protect from electrostatic discharge.
ESD wrist strap	Protect from electrostatic discharge.
Multimeter	Test the insulation of a cabinet, connectivity of a cable, and electric performance specifications of a device, such as voltage, current, and resistance.
Fiber extractor	A fiber extractor helps you to replace LC fibers, pluggable optical modules, and unshielded network cables.

For 18000 series storage systems, adjustable guide rails are preinstalled in the bays before delivery. Four bags of screws, which are used to secure these adjustable guide rails for capacity expansion, are placed in the lower left corner and lower right corner (two bags on each side) of each bay. Use these screws as needed during the installation and put back the remaining screws for future capacity expansion.

Table 4-2 lists the software required for capacity expansion.

Table 4-2 Software required for capacity expansion

Software	Used To	Obtain From
SSH tool	Log in to a storage system and transfer files between the maintenance terminal and the storage system.	This document uses the PuTTY software as an example. You can download PuTTY from chiark website. Use the latest version of PuTTY; otherwise you may fail to log in to the storage system.
SmartKit NOTE: This document uses SmartKit (formerly named Toolkit) as an example. SmartKit is used to deploy, maintain, and upgrade storage systems. It provides multiple storage products with service configuration functions, including upgrade assessment, inspection and information collection, patch installation, and batch upgrade. Download SmartKit and the capacity expansion tool before expanding capacity.	Check the health status of the overall storage system before the capacity expansion. Perform the capacity expansion.	Upgrade the tool to the latest version. Log in to Huawei enterprise website https://support.huawei.com/enterprise/en/index.html, and download the latest SmartKit, capacity expansion evaluation tool, and capacity expansion tool.
