Getting Started Disk Management

If Retry is set to zero, the SCS can no longer be used; it will wait indefinitely for the configuration file to
download.
2.6 Disk Management
The SCS contains three filesystems:
/flash 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.
/ram 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.
/rom The ROM disk is read-only and cannot be modified by users.
In addition to the onboard Flash disk, the PC card slots on the SCS200 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 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:
Figure 2-33: Creating a New Directory on the Flash Disk
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:

The complete syntax of the Disk command is available on page 12-5.
Local>> DISK MKDIR /flash/customapps/
Local>> DISK LS -l /flash
