Few
customers have MC1500 and want to upgrade their controller to SD-R5.3

If the available space on /dev/root is less than 150 MB or greater than 67%, the upgrade is not possible.
To free up more space:
- Delete the current firmware version in flash.
default# delete flash: <firmware-version>
- Delete the unnecessary files from /opt/meru/images like meru.gather.xxx (diagnostics)
default# delete <filename>
- Still
if there is not enough space, use meru-5.1-103-1GBUpgrade-MC1500.tar
feature file as this feature installation will expand current main file
system with sda2 partition which has been taken by old SD-R4.0 build.
However after this the controller cannot be downgraded to SD-R4.0.
Step 1: From IOSCLI, copy meru-5.1-103-1GBUpgrade-MC1500.tar file from release server.
default(15)#copy ftp://<username>:<pwd>@<ftp –ip>/meru-5.1-103-1GBUpgrade-MC1500.tar .
Step 2: Check if the pre-feature is installed successfully.
default(15)# show flash
5.1-99
4.0-165
5.1-103-1GBUpgrade
Step 3: Run <upgrade feature “5.1-103-1GBUpgrade” > to install MC1500 1GB feature.
default(15)# upgrade feature 5.1-103-1GBUpgrade
Step 4: Logout from the current session and login again to take effect the feature installation.
default(15)# exit
Step 5: Check the available space on the flash
default(15)# show file system
Step 6: copy SD-R5.3 image to the flash
default(15)# copy ftp://<username>:<pwd>@<ftp –ip>//meru-5.3-132-MC1500-rpm.tar .
Step 7: Upgrade MC1500 with 1GB Flash size to SD-R5.3-132 build.
default(15)# show flash
5.1-99
5.3-132
default(15)# upgrade controller 5.3-132
Note: meru-5.1-103-1GBUpgrade-MC1500.tar feature file can be used only if the controller firmware version is either 5.1 and higher.
