PV COPIES IN BAND DISTRIBUTION

hdisk1 016:000:000 100% 000:000:016:000:000

and in the processlv I got

$ lslv -l Processlv
Processlv:/opt/IBM
PV COPIES IN BAND DISTRIBUTION
hdisk0 080:000:000 5% 076:004:000:000:000
hdisk1 080:000:000 55% 036:044:000:000:000

There is no problem for the differences, because I think in the processlv have to be 100% [...]

Are you concerned because of the "low" percentage value? Well, that is just an indicator how good your LV matches its position on the disk according to its definition. E.g. AIX uses ranges on disks: edge-middle-center-inner_middle-inner_edge with a preference to use center and middle areas first (to reduce movement of read-write heads). If you define that an LV has to be placed in center and all PP fit in there you get the 100%. If some or all PP in center area are taken already your LV goes somewhere else and the percent value is getting smaller.
With SAN storage this is of no interest. It may be of interest on SCSI disks e.g. in most cases for reasons of performance. One can change the LV's properties with chlv and run a reorgvg to make it look "nicer" but as long as the LV's location on the local disks does not impact performance in a bad way I'd just leave it alone.

I've looked a little but haven't found a solid answer, assuming there is one. What's better, hardware mirroring or ZFS mirroring? Common practice for us was to use the raid controllers on the Sun x86 servers. Now we've been using ZFS mirroring since U6. Any performance difference? Any other...

rootvg mirrored

I want to increase the size of /tmp by 1GB I know that the command is chfs -a size=+1G /tmp But the rootvg is mirrored and when I do a lsvg -p rootvg, I could see 2 disks. Will there be any impact if I increase the size of /tmp when the rootvg is mirrored ? Please advise.

envext

ENVEXT(1)						  The Canonical Csound Reference						 ENVEXT(1)

NAME

       envext - Extracts the envelope of a file to a text file. .

SYNTAX

	   envext [-flags] soundfile

	   csound -U envext [-flags] soundfile

INITIALIZATION

       soundfile - Name of the input soundfile.

       The following flags are available for envext (The default values are stated in parenthesis):
	   -o fnam Name of output filename (newenv)
	   -w size (in seconds) of analysis window (0.25)

       The envext utility generates a text file containing time and amplitude pairs by finding the absolute peak within each window.

EXAMPLE

       Using the command (while in the manual directory):

	   csound -U envext examples/mary.wav

       will produce the a text file containing the following:

	     0.000   0.000
	     0.000   0.000
	     0.250   0.000
	     0.500   0.000
	     0.750   0.000
	     1.249   0.170
	     1.499   0.269
	     1.530   0.307
	     1.872   0.263
	     2.056   0.304
	     2.294   0.241
	     2.570   0.216
	     2.761   0.178
	     3.077   0.011
	     3.251   0.001
	     3.500   0.000

       Which shows the time for the peak amplitude within each measured window.
