Please be more explicit about what errors you want to cause to send an additional email.

Is it an error that you are invoking replacepv with three operands while the man page only specifies what happen when two operands are given? For example, when you read the 1st line from test.list (setting DISK1 to hdisk0), you will be running the command:

Code:

        sudo  replacepv hdisk0 hdisk6 hdisk0  | tee -a ERR.OUT

Is that an error? Does the above replacepv command complete successfully? Does it print any diagnostic messages? Does it write anything into ERR.OUT?

Is it an error when your grep command matches two or more lines and you only process one of those lines? For example, when you read the 2nd line from test.list, the command:

Code:

        grep hdisk1 NEWDISK.list

will match the following lines from NEWDISK.list:

Code:

rootvg hdisk7 hdisk1
optvg  hdisk10 hdisk4

but you only read the 1st matched line and run the command:

Code:

        sudo  replacepv hdisk1 hdisk7 hdisk1

ignoring the 2nd line and not running the command:

Code:

        sudo  replacepv hdisk1 hdisk10 hdisk4

Is that an error? Or, is it an error that the above grep command matched hdisk10 on the 2nd line when it should not match hdisk10 when I assume you only wanted exact matches for the word hdisk1?

Or, did you just want to mail any lines appended to ERR.OUT (even though ERR.OUT does not contain any diagnostic messages that might have been written to explain what errors had been detected)?
