Code:
   mk_netboot    = yes
   missing       = "network boot image"
   missing       = bos.64bit
   missing       = bos.diag
   [...]

You need to include the filesets reported as "missing". A SPOT (shared product object tree) is like a shared, NFS-mounted "/usr"-tree and therefore needs several core packages included otherwise it couldn't act in this function. If you do not have them in your LPP-source you should include them there either.

Further, this is only a suspicion but it seems you manipulated the exports file yourself. As a rule of thumb: don't do that! At least don't do that with anything in or below the directory with the NIM resources. It might solve one specific problems but usually introduces several dozens of new ones in the process.

Another frequent problem is the definition of the NIM networks. NIM works (in parts) on top of the bootp protocol and therefore has to specifically check clients on other networks if they can be booted with it (this means testing the switch/router for being able to act as a "bootp relay agent", originally called "bootp forwarding agents", see RFC951, RFC1532, RFC1542, etc.) which is why for each network a client could be on a "NIM network" has to be defined.

Finally, when you allocate a resource to a client and it doesn't work somehow in most cases - but not all! - the resources are deallocated. Alas, rather frequently they remain allocated and not even a deallocation with the "force" option will straighten them out. NIM is quite untrustworthy in this regard and i hate to say it but it didn't improve much over the ~20 years i work with it. It is sometimes a good idea to simply delete the respective machines object and recreate it from scratch.

Right now i am not at the office so i cannot look it up but tomorrow i can post you a simpler way to create SPOTs, so stay tuned.

I hope this helps.

NAME
spottopgm - convert SPOT satellite images to Portable Greymap format SYNTAX
spottopgm [-1|2|3] [Firstcol Firstline Lastcol Lastline] inputfile OPTIONS
-1|2|3 Extract the given colour from the SPOT image. The colours are infra-red, visible light and ultra-violet, although I don't know which corresponds to which number. If the image is in colour, this will be announced on standard error. The default colour is 1. Firstcol Firstline Lastcol Lastline Extract the specified rectangle from the SPOT image. Most SPOT images are 3000 lines long and 3000 or more columns wide. Unfortu- nately the SPOT format only gives the width and not the length. The width is printed on standard error. The default rectangle is the width of the input image by 3000 lines. DESCRIPTION
Spottopgm converts the named inputfile into Portable Greymap format, defaulting to the first color and the whole SPOT image unless speci- fied by the options. INSTALLATION
You must edit the source program and either define BIG_ENDIAN or LITTLE_ENDIAN, and fix the typedefs for uint32_t, uint16_t and uint8_t appropriately. BUGS
Currently spottopgm doesn't determine the length of the input file; this would involve two passes over the input file. It defaults to 3000 lines instead. Spottopgm could extract a three-color image (ppm), but I didn't feel like making the program more complicated than it is now. Besides, there is no one-to-one correspondence between red, green, blue and infra-red, visible and ultra-violet. I've only had a limited number of SPOT images to play with, and therefore wouldn't guarantee that this will work on any other images. AUTHOR
