Compact flash devices

The file system is based on a DOS file system. The 7210 SAS devices provide several storage options, including internal flash and USB.

The following compact flash devices are supported:

internal non-removable flash, cf1:\
external removable compact flash or external removable SD card, cf2:\
external USB slot, uf1:\

The device names are relative device names in that they refer to the devices local to the control processor running the current console session. As in the DOS file system, the colon (‟:”) at the end of the name indicates it is a device.

The following table lists the storage locations available on specific 7210 SAS platforms.

Table: Storage locations on 7210 SAS platforms
7210 SAS platforms	Storage locations
7210 SAS platforms	cf1:\	cf2:\	uf1:\
7210 SAS-Mxp	✓	✓^¹	✓
7210 SAS-R6	✓	✓^¹	✓
7210 SAS-R12	✓	✓^¹	✓
7210 SAS-S 1/10GE	✓	✓^²
7210 SAS-Sx 1/10GE	✓	✓^²	✓
7210 SAS-Sx 10/100GE	✓	✓^²	✓
7210 SAS-T	✓	✓^¹	✓

In addition to user-added files and directories, the number of files in the root directory can also increment when the admin save or bof save commands are issued. The system enforces a threshold limit of 80 entries (files and directories) for contents of the root directory on cf1:\; there is no restriction on the number of files and directories that you can add in the subdirectories. A trap (tmnxRootDirFull) is generated if the threshold limit is exceeded, and a warning is generated for each new file or directory created in the root directory on cf1:\ after the threshold limit is exceeded.

Note:

User intervention is required when the system displays the threshold exceeded event (tmnxRootDirFull). You are required to clean the root directory on cf1:\ and ensure that the number of entries (files or directories) is below the enforced threshold limit of 80 entries. Remove unnecessary files and directories from the root directory or move them to a subdirectory that you have created under the root directory. The system does not generate a warning when the number of files and directories is reduced below the threshold limit.

Use the file dir cf1:\ command to determine the number of entries (files or directories) in the root directory. For example, in the following listing, the total number of entries in the root directory (file and directories) is 14 files + 2 directories = 16.

Example

*A:7210-SAS #

*A:7210-SAS #file dir

 Volume in drive cf1 on slot A is /flash.

 Volume in drive cf1 on slot A is formatted as FAT32.
