Hi Robert: cyl 0 trk 0 rec 1 contains ipl text as need by the hardware ; 0 0 2 contains 4k of SAPL code; 0 0 3 label info; 0 0 4 alloc data. The rest of sapl is tucked away on cyl 0 track 13 and maybe 14. Track 2 seems to be quite unused in a non-CSE system such as mine.

Subject: [IBMVM] One last question, before aiming at my foot...
What is the layout of Cylinder zero on the 520RES pack? What tracks
contain SAL, and are there other tracks reserved there? Are there any
unforeseen issues with having the 520RES appear as an XLINK shared
volume?
XLINK FORMAT defaults to track 2 in cyl 0, which would probably work for
every other drive, but I'm unsure about the fit for 520RES. Any hints,
opinions, or outright reasons for not protecting links on 520RES? (We do
share a single 520RES between two systems now, so link protection is
something we'd like to implement for it....)
