ChangeLog

Supported installation targets

A setup goal is a storage device that shops CentOS and boots the system. CentOS helps the next set up targets for AMD64, Intel 64, and 64-bit ARM techniques:

Storage linked by a regular inner interface, comparable to SCSI, SATA, or SAS
BIOS/firmware RAID devices
NVDIMM devices in sector mode on the Intel64 and AMD64 architectures, supported by the nd_pmem driver.
Fibre Channel Host Bus Adapters and multipath devices. Some can require vendor-provided drivers.
Xen blocks devices on Intel processors in Xen digital machines.
VirtIO blocks devices on Intel processors in KVM digital machines.

System specifications

The CentOS setup program robotically detects and installs your system’s {hardware}, so you shouldn’t have to provide any particular system info. However, for sure CentOS set up eventualities, it is strongly recommended that you simply report system specs for future reference.

These scenarios include:

Installing CentOS with a personalized partition layout

Record: The mannequin numbers, sizes, sorts, and interfaces of the laborious drives hooked up to the system. For example, Seagate ST3320613AS 320 GB on SATA0, Western Digital WD7500AAKS 750 GB on SATA1.

Installing CentOS as an additional operating system on a current system

Record: Partitions used on the system. This info can embrace file system sorts, device node names, file system labels, and sizes, and lets you determine particular partitions throughout the partitioning course. If one of many working techniques is a Unix working system, CentOS might report the device names otherwise. Additional info might be discovered by executing the equal of the mount command and the blkid command, and within the /and so on/fstab file.

If several working techniques are put in, the CentOS setup program attempts to robotically detect them and configure the boot loader in addition to them. You can manually configure extra working techniques if they aren’t detected robotically. See Configuring boot loader in Configuring software options for more info.

Installing CentOS from an image on a local hard drive

Record: The laborious drive and listing that holds the image.

Installing CentOS from a network location
If the network needs to be configured manually, that’s, DHCP is just not used.

Record:

IP deal with
Netmask
Gateway IP deal with
Server IP addresses, if required

Contact your network administrator in case you want help with networking requirements.

Installing CentOS on an iSCSI goal
