2-5

Verifying Contiguous Free Space on a Flash Volume

You must determine the amount of contiguous free space required on a flash card

to accommodate your customized Version 14.xx router software image and

configuration files. The amount of contiguous free space available on the target

flash volume must be greater than the combined size of your customized Version

14.xx image and associated files (such as config, ti.cfg, install.bat, and, if

appropriate, a Version 14.xx PROM image).

To verify the amount of contiguous free space available on a selected volume, see

the fields at the bottom of the Site Manager Router Files Manager window

(Table 2-2

Compacting a Flash Memory Card

Before upgrading the router, you should compact a flash memory card to ensure

that the flash card has enough contiguous free space to accommodate the new

Version 14.xx software image.

Compact your flash card during off-peak hours, if possible, because of the heavy

resources required (FRE memory and CPU cycles). Do not remove a flash card,

hot-swap a slot, or reset a slot during flash card compaction, because the card will

become corrupted, causing loss of data.

Table 2-2. Determining Contiguous Free Space on a Flash Card

Field Meaning

Total Size Total number of bytes (used and unused) on the volume

Available Free Space Number of unused bytes on the volume

Contiguous Free Space Number of unused bytes in the largest block available on the

volume. This space is actual usable memory.

Caution:

A flash compaction operation may take up to 12 minutes on an AN

router. Do not turn the AN router on and off during compaction or you will

corrupt the flash card and the AN router will not boot.
