Issue

  • Frequent SRAM dumps on multiple ports causing disconnects on Esxi host.
  • EMS logs show:
Wed Sep 20 16:26:17 +0400 [Netapp04: fct_tpd_thread_7: scsitarget.fcp.dump:debug]: FCP target SRAM dump generated for adapter 3x, fct_tpd_check_hung_commands: Command termination hung. cmd:0xfffff81e7c951b40 (state=0xa, flags=0x2,ctio_sent=2/3, RecvExAddr=0x2a71, OX_ID=0x325b, RX_ID=0xffff, SID=0x5b0d17) 
Wed Sep 20 16:26:18 +0400 [Netapp04: fct_tpd_thread_7: callhome.fcp.sram.dump:error]: Call home for FCP SRAM DUMP.
  • Replacing cable and SFP on ONTAP ports does not fix the issue.
  • The SFPs are of optimal power on switch and ONTAP:
RXPower:    -0.8    dBm (827.5uW)
TXPower:    -0.1    dBm (983.4 uW)
  • Errdump logs on switch show timeouts:
