The script, FindBadBlocks.sh utilizes the -bmsr function to enumerate all bad blocks and report them by slice (the
equivalent of a partition). This, in turn, can be used by the system administrator to determine whether or not a repair
is warranted for any particular volume. This script was run against the same Solaris 10 system that supplied the scan
results shown above .

1.53.1 Finding Bad Blocks Script
This is the source code for the FindBadBlocks.sh script shown in previous section. It has only been tested under
Solaris 10, but serves as an example of what can be done to extend the functionality of the -bmsr command.
