IOS XR platform routers (such as CRS ), the storage media (or disk) is more dir or Show FileSystem can see which disks, as shown below, for beginners, may be confused, so many disks, what is the use of each? What's the difference?

Some of the content has not been understood for the time being, the following is a description of the already understood column, as follows

1, Bootflash storage is the IOX Boot Program (System), the boot program between Rommon and IOX ;

2, Disk0,disk0a,disk1,disk1a: Equivalent to the computer's C disk, for storing system files, multiple disks can be configured to mirror backup ; Ordinary documents are not recommended to be stored on the disk manually;

3, harddisk,Harddiska,harddiskb: equivalent to the computer in the D- disk, can store a variety of user files;

4, Lcdisk0,lcdisk0a: estimate the line card on the disk;

5, Location: Through this parameter, you can view the disk information of other cards, such as command dir bootflash:location 0/2/cpu0, if the location parameteris not added , The default is to view the main engine board information;

6. NVRAM : Rommon where the parameter information is stored, such as the register value, IP address, TFTP address and so on;

IOS XRand theIOSThere's a difference,IOSPlatform foriOSfiles are stored inFlashin the case of a file, when the router is running, it needs toiOSThe file is read into memory, so when the router is running properly, delete theFlashin theiOSfile does not affect the continued operation of the router (but the next reboot does notiOSfile, it must be impossible to start);IOS XRplatform is to use an installation package (popularly calledMini), it will unzip into a lot of directories and files, stored inDisk0, during the operation of the router, it can not be arbitrarily deleted.
