The E120 router and the E320 router can have a second flash card installed with its SRP modules. Device names are reserved for the E120 and E320 router flash card slots: disk0, disk1, standby-disk0, and standby-disk1. For backward compatibility, you can use the name standby, which is equivalent to standby-disk0. You can use the second card (disk1 or standby-disk1) only for storage of core dump (.dmp) files. When the a card is installed and mounted as disk1 or standby-disk1, all .dmp files are automatically stored on this card. You must use the card mounted as disk0 or standby-disk0 for all other file types. Core dump files are stored on disk0 or standby-disk0 only when a second card is not installed.
The copy, dir, delete, and rename commands all recognize the device names, as in the following examples. Disk1 and standby-disk1 accept only dump files. This means that you can copy only .dmp files to the second disk, delete only .dmp files from the second disk, and rename only .dmp files on the second disk.
host1#copy reset05.dmp server2:reset05.dmp host1#copy disk0:051802.dmp server2:reset05.dmp
host1#delete disk1:reset05.dmp host1#delete standby:reset05.dmp host1#delete standby-disk0:reset05.dmp host1#delete standby-disk1:reset05.dmp

Because the device names are reserved, if you upgrade from a release where you previously used those names for remote hostnames, an error message appears when you try to use that remote hostname:
- %ambiguous file name, reserved disk device name "disk1"
must be removed from host table
To prevent corruption of flash cards, always issue the halt command before you remove an SRP module. See Removing an SRP Module. Issue the halt command before you remove a flash card installed as disk 0 or standby disk 0. Flash cards installed and mounted as disk1 or standby disk1 can be safely removed by issuing the no mount command for the card and then ejecting the card. Always reboot the router using the rebooting procedure. See Booting the System . Do not reboot the router by switching it off and on.
