Checking the SW Media integrity (Iso # Checksum)

Application DVD Checksum

Note:

Refer to the MR Service Pack Software Matrix (DOC1667089), available from the online documentation library and make sure the necessary service pack media (if any) is available. Do not start the software load until this media is available.

Insert the Application DVD into DVD drive.
Open a command window.
Note: The Shell window can only be launched when the EA3 user is included in the authorized EA3 group. Users not in this EA3 group will not have access to launch the Shell window. If you are not logged in as the proper logon user, log out and then log back on as the correct EA3 user with the authorized permissions.
Login as root with Signa default root password and run the following two commands:
Note: If the checksum does not match with the data from the MR Service Pack Software Matrix (DOC1667089), STOP the installation process and contact GEHC Services for support. Note that the output of the dd command “x.x MB/s (data transfer rate)” below may vary; this specific param does not have to match up with the number as shown below. Due to the data size of the application DVD, the dd command may take up to 15 minutes to complete.
1. # isosize -x /dev/sr0
```
 sector count: 1995763, sector size: 2048
```
  Note: The sector count and sector size here should be used in the dd command below.
2. # dd if=/dev/sr0 bs=2048 count=1995763 conv=notrunc,noerror | sha256sum
