Yes indeed, you are correct.
But, again there are few things you have to consider before creating SEA, you mentioned that these are Blade Servers, so how are you viewing them, through HMC or IVM? How many VIOS you have on each Blade?

If you have only one VIO on each blade, then SEA holds no good, coz it won't failover. If you have two VIOS, then only you are good to go for SEA.

Now, considering you have two VIOS, we have to figure out which virtual adapter (out of the 4) is your primary adapter and which is control channel adapter. You can check the profile (of virtual adapter) if a adapter has been check as access external network, and given a trunking priority then it is your primary adapter, for control channel adapter you WONT select access external network, and most shops give it a vlan no of 99 (purely environment based, so such standard), so as to distinguish control channel adapter from others.

You cannot use smitty (in rksh), you have to use mkdev command to create SEA.
$ mkvdev -sea "real adapt" -vadapter "primary virt adapt" -default "primary virt adapt" -defaultid "PVID" -attr ha_mode=auto ctrl_chan="control channel adapt"

Hope this helps.

ppmtosixel

ppmtosixel(1)                                                 General Commands Manual                                                ppmtosixel(1)

NAME

       ppmtosixel - convert a portable pixmap into DEC sixel format

SYNOPSIS

       ppmtosixel [-raw] [-margin] [ppmfile]

DESCRIPTION

       Reads  a  portable  pixmap  as input.  Produces sixel commands (SIX) as output.  The output is formatted for color printing, e.g. for a DEC
       LJ250 color inkjet printer.

       If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled.  A printer control header and a color assignment table
       begin the SIX file.  Image data is written in a compressed format by default.  A printer control footer ends the image file.

OPTIONS

       -raw   If  specified,  each  pixel  will  be explicitly described in the image file.  If -raw is not specified, output will default to com-
              pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands.  A raw file is often an order  of  magni-
              tude larger than a compressed file and prints much slower.

       -margin
              If  -margin  is not specified, the image will be start at the left margin (of the window, paper, or whatever).  If -margin is speci-
              fied, a 1.5 inch left margin will offset the image.

PRINTING

       Generally, sixel files must reach the printer unfiltered.  Use the lpr -x option or cat filename > /dev/tty0?.

BUGS

       Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion.  If the original PPM maxval was
       greater  than  100,  rescaling  also reduces the image depth.  While the actual RGB values from the ppm file are more or less retained, the
       color palette of the LJ250 may not match the colors on your screen.  This seems to be a printer limitation.
