Hello,
I have got an ACE box runing c4710ace-t1k9-mz.A5_1_2.bin and i was trying to downgrade the code to A4_2_2.bin.When i tried to copy the .bin file to :image, it terminates the copying process in the middle with the following message.
Step 1:
###############################################################################################################
local: /mnt/cf/c4710ace-t1k9-mz.A4_2_2.bin: Read-only file
ACE-4710/Admin(config)# boot system image:c4710ace-t1k9-mz.A4_2_2.bin
Validating system image...
Error! failed to set boot image: bad CRC
Step 2:
As a next step, i tried to delete the .bin file and upload again, but i couldnt delete it.
ACE-4710/Admin# delete image:c4710ace-t1k9-mz.A4_2_2.bin
delete: cannot remove 'c4710ace-t1k9-mz.A4_2_2.bin': Read-only file system
ACE-4710/Admin#
So i reloaded the ACE and was able to delete the partially copied file, but the same error happenes again (step1).
I followed the below document and formatted the flash
http://www.cisco.com/en/US/docs/interfaces_modules/services_modules/ace/vA5_1_0/configuration/administration/guide/managesw.pdf
read section
Reformatting the ACE Appliance Flash Memory
Step 3:
ACE-4710/Admin# FORMAT flash:

including startup configs for all the contexts and reboot
the system!!

Final: After formatting, the device got crashed and went to GRUB> mode. ( did not boot into the original image or recovery image)
I would like to know.
1. why the copying process failed with - " local: /mnt/cf/c4710ace-t1k9-mz.A4_2_2.bin: Read-only file" message
2. why i couldnt delete the partially copied file with out device reload - " delete: cannot remove 'c4710ace-t1k9-mz.A4_2_2.bin': Read-only file system"
3. Why it crashed after format
Note: The image i used is not corrupted, i was able to load the same image to another box.
No network connectivity issues.
I use local admin account for the above activity.
dir image: shows enough free space
