Getting Started

2.6 Disk Management

The SCS contains three filesystems:
/flash
/ram
/rom
In addition to the onboard Flash disk, the PC card slots on the SCS200 and SCS400 can be used with ATA
flash cards and hard-drive PC cards for portable storage of local files.
In some instances, you may need to edit a file on another machine and then FTP it to the SCS. Use your FTP
client software to form a connection to the SCS (using the SCS's resolvable name or IP address). You can
then transfer files to (put) and from (get) the /flash, /pccard, and /ram disks.

2.6.1 Flash Disk

The Flash disk (/flash), rewriteable memory, should be used to hold any data that you want the SCS to save
after it is rebooted. Because power glitches can affect data integrity, important files on /flash should be
backed up on an ATA flash card or on another server.
The Disk commands can be used to manage files on the Flash disk. For example, the following command
creates a new directory on the Flash disk that could be used for custom application files:
Local>> DISK MKDIR /flash/customapps/
To view all of the files and directories currently on the Flash disk, enter Disk ls with or without flags. The
following example will display all the files as well as the modification date, size, owner, and permissions:
Local>> DISK LS -l /flash
The complete syntax of the Disk command is available on page 12-182.

2.6.2 ATA Cards

Once an ATA flash disk or hard-drive PC card is formatted (using the Disk Format /pccard command), the
card can be used the same as the on-board Flash disk. Files on the card can be references as "/pccard1/
directory/filename."
The SCS does not support PC card hot-swapping. Any time you insert a PC card
Note:
into an SCS PC card slot, you must reboot the SCS.
Flash is rewriteable memory that allows you to customize your SCS. Any data
that you want the SCS to save after it is rebooted should be stored on the Flash
disk.
The RAM disk stores temporary information. The SCS will hold information
stored on this disk until it is powered off or rebooted. At startup, the RAM disk
will be empty. FTP connections to the SCS automatically use the RAM disk as
the default working directory. The RAM disk size is 512 Kbytes.
The ROM disk is read-only and cannot be modified by users.
