Need to understand vmoprcmd command

Hi,

I am new to Netbackup and trying to learn and understand it, so i would really appreciate if you can help me with some questions on below mentioned vmoprcmd output.

# vmoprcmd 

						 HOST STATUS
Host Name								Version   Host Status
=========================================  =======   ===========
hamex									 600000	ACTIVE

							PENDING REQUESTS

	hamex				 {3,1,1,2}						 TLD

IBM.ULTRIUM-TD1.004	No	No					 No	 hcart

	hamex				 {3,1,1,7}						 TLD

IBM.ULTRIUM-TD2.005	Yes	 Yes	J945L2		Yes	hcart2
	hamex				 {3,1,2,1}						 TLD

IBM.ULTRIUM-TD2.006	No	No					 No	 hcart2
	hamex				 {3,1,2,2}						 TLD

# vmoprcmd -downbyname IBM.ULTRIUM-TD1.004 -path {3,1,0,7}

Q1. Under Host Name we see "hamex", may i know hamex is the media server or master server . So what does basically host name denote here?

Q2. Can you please explain Drive Name, what does all parts of "IBM.ULTRIUM-TD2.005" denotes here.

Q3. What is the drive index and where can i find it in this command output?

I would really appreciate if you could help me with these questions.

Thanks
