  • Multimode IFGRP(LACP)

Issue

  • After performing a storage failover (takeover/giveback) or node reboot, the IFGRP status on node node-01 shows as none and all member ports (e0e, e0f, e0g, e0h) are down

Example:

node-01(EMS)
[node-01:nblade1:netif.linkDown:info]: Ethernete0e: Link down, check cable.
[node-01:nblade1:netif.linkDown:info]: Ethernete0f: Link down, check cable.
[node-01:nblade1:netif.linkDown:info]: Ethernete0g: Link down, check cable.
[node-01:nblade1:netif.linkDown:info]: Ethernete0h: Link down, check cable.

[node-01:vifmgr:vifmgr.reach.noreach:notice]: Network port e0e on node node-01 cannot reach its expected broadcast domain Default:10g_domain.

node-01(SYSCONFIG -A)
SFP Vendor P/N:    FTLX8574D3BCV-IT

node-01(IFGRP.XML)
Node node-01
Interface Group Name a1a
Distribution Function ip

  • The issue can be cleared by reseating the cable, but it recurs after subsequent takeover/giveback tests
  • SFP module replacement does not resolve the problem
  • The storage controller and SFP modules are confirmed to be healthy and compatible
  • The issue is not observed during manual LIF migration tests
