Perform the following procedure to resolve the CDROM invalid error:

As a root user, run the following commands on the server where the upgrade failed because of the CDROM invalid error:
```
cd /usr/TKLC/appworks/sbin
```
```
./backout_restore
```
```
init 6
```
Before upgrade, verify if /var/TKLC/upgrade has an iso file and if the size of the file is appropriate.
In case of any server issue, instead of ASU, perform upgrade from Platcfg by performing following steps:
1. Copy the iso file to the following path /var/TKLC/upgrade.
2. Provide required permission to the iso file.
3. Perform upgrade from platcfg.
If the upgrade fails, perform the following steps on the server:
1. Copy the iso file to the following path /var/TKLC/upgrade.
2. Provide the required permission.
3. If there is an error, remove the last entry from the revision file.
4. Skip the early upgrade check by running the following command:
```
sudo su -
        sudo su touch /tmp/ignoreDsrEarlyUpgradeChecks echo "IGNORE_EARLY_CHECKS=1" >
        /var/TKLC/log/upgrade/tmp_upgrade.conf chmod 777
        /var/TKLC/log/upgrade/tmp_upgrade.conf
```
Start the upgrade from platcfg.
