Installing the OS
Restrictions and guidelines
•
The firewall of the OS installed through iFIST is disabled by default.
•
When you install a new OS on the local server with an OS, the old OS will be overwritten.
•
To avoid OS installation or startup failure, if you change the storage controller mode to HBA in
Legacy mode, you must specify the first physical drive as the first boot option.
•
To install an OS on a server in UEFI boot mode, make sure only the system disk contains a
UEFI partition. OS installation might fail if a UEFI partition exists on a non-system disk.
•
To avoid OS installation failure, do not install the OS on a drive of 2 TB or a larger capacity as a
best practice.
•
Before OS installation, make sure only one OS image is mounted to the server. If more than one
bootable media are mounted, the server might fail to identify the correct boot media, and OS
installation might fail as a result.
•
If a USB disk is the boot media, the file name and path name of the OS image must meet the
following requirements:

Contain only letters, digits, hyphens (-), underscores (_), dots (.), and spaces.

Do not contain consecutive spaces.
•
If a USB disk as the boot media is removed and re-installed, refresh the webpage for the
system to identify the boot media.
•
Do not remove the boot media before the OS installation is complete.
