nmicic / extract_egtpc_peers.awk
Last active December 19, 2024 07:58
get egptc peers list from SSD or show egtpc peer output
#!/usr/bin/awk -f
#Use: chmod +x ./extract_egtpc_peers.awk;
# cat SSD.txt | ./extract_egtpc_peers.awk
# Example to use on multiple SSD's:
# cat SSD1.txt | ./extract_egtpc_peers.awk > peers1.txt
# cat SSD2.txt | ./extract_egtpc_peers.awk > peers2.txt
# cat SSD3.txt | ./extract_egtpc_peers.awk > peers3.txt
# then agregate outputs into one:
# cat peers*.txt | sort | uniq > all.txt
# -> if SSD1,2,3 are from different nodes, then all.txt will have agregated view from all.

RJIO MOP 698327065

First execute

  1. prior MOP commands
  2. debug shell card4 ipsecmgr task kill
  3. if no progress then excute: dcardmgr task kill ( NOTE: here execute again 2 after)
  4. after MOP commands
  5. if no change then reboot card 4 ( not migration )
  6. run one more time after MOP commands ( this has to be done anyways )
  7. if there are any issue alert the TAC

# ./crypto_chip_detect.sh support_summary
#
# In short script check Alloc-Free for crypto counters which will be very low for working cards - usually less then 100 or more around 10.
# Note threshold is set to 3000, in some corener cases during very high load may go to this value, but will go back in second back to low value.
# BUT, if you see 4 lines: Issue deteceted delta for same card then it is 100% crypto chip issue.
# This threshold is assumed as we are little bit bellow 4K buffers. In 21.28.mX buffers are increased to 4k. In older version this could be close to 1K.
