Why does not the recognized supervisor?
Without reload the switch, any way to recognize the supervisor?

Well your last output indicates the hardware module in slot 4 is not recognized. That will certainly prevent it from operating as a hot standby.
The command once it had the IOS upgrade completed should have been "redundancy reload peer". Reference.

Also, notice your output "BOOT variable =" shows no boot order. Was this the only file in bootflash. If not, it likely booted to the "first" image found. Also, it appears your secondary supervisor had not finished booting or failed to boot after you reset it. To echo what Marvin said, your initial problems with not going to a hot standby were because you were on two different major IOS releases, 15.0 on one and 15.1 on the other (IOS XE 3.01 on one and 3.04 on the other). You can be on different patches of the same major release, but not on different major releases or capabilities, i.e. IP Base on one and Adv Enterprise on the other (pre-Universal image issue). What do you show from a console connection of the standby Sup, is it booted to IOS and the right IOS?

There is crash info file been generated on the device if in case you get that would be helpfull.
your switch had crashed with the following errors present in the crash log:
8/000044: Apr 25 16:37:12.824 GMT-5: %SYS-2-CHUNKBADMAGIC: Bad magic number in chunk header, chunk 88A0AC70 data 88A130A8 chunkmagic 5DA3C78B chunk_freemagic 0 -Process= "Check heaps", ipl= 0, pid= 7
-Traceback= 1#d1c16a2e6f8ceec1892aa2e47e2a2618 :10000000+FCC0E4 :10000000+1BEE4E4 :10000000+1BEE794 :10000000+1C168F00
This is a memory corruption issue. Within IOS, each chunk of memory has
a "header" followed by the data itself. The header describes various
attributes about the data, including what type of data is held within
the chunk. Any chunks of memory that are freed are given what is known
as a "CHUNKFREEMAGIC" code within the header. In your case, we have
determined that this field had been corrupted, varying only a few bits
from the expected value.
After contacting internal groups that support the Supervisor 7E, I have
been referred to bug CSCtr35883, which is a similar sort of memory
corruption on your version of IOS, identical except for the fact that
the individual who originally hit the bug had seen corruption in a
different field. from your crash logs, it appears that you are definitely running
into this defect. Apparently, several bits are being written into the
corrupt chunk of memory from the previous chunk that comes just before
it, a phenomenon known as "overflow."
