What issues should be considered for any ONTAP switch maintenance
Applies to
- ONTAP 9
- Cluster Interconnect Switches
- MetroCluster IP Switches
Answer
Defects with fixed releases
- CONTAP-47128: Corrupted FlexGroup packets can create invalid FlexGroup objects which might cause disruption to ONTAP
- CONTAP-70312: Link goes down on XL710 Ethernet port when the node boots
- CONTAP-72511: A MetroCluster IP node might unexpectedly reboot after a link down event
- CONTAP-80258: Cluster interconnect management LIF misconfiguration
- CONTAP-82891: For ONTAP health monitoring of Cisco switches, SNMPv2 traffic might still be seen after switching to SNMPv3 for monitoring
- CONTAP-88324: Node disruption occurs and the partner node fails to takeover due to invalid pointer
- CONTAP-95651: T6 NIC fatal error for an HA Ethernet port results in an incomplete storage failover and inability to give back
- CONTAP-97016: Malformed packets observed after a 40GbE to 100GbE port speed conversion on T6 port (also fixed in earlier releases with CONTAP-166912)
- See additional information at SU540: Chelsio T6 NIC errors cause system shutdown when upgrading from 40G to 100G network switches
- CONTAP-110409: XL-710 NIC receive queue may become hung
- CONTAP-195893: When cluster ports are disconnected from one of the redundant switches vifmgr fails and new connections cannot be set up
- CONTAP-230184: Improved HA handling when a T6 card reports a fatal error
- CONTAP-249770: NVIDIA SN2100 switches shown as "unsupported"
- Bug 1527321: Ports on X1151A do not come online when using optical cables to connect to Cisco 9336C-FX2 switches resolved by Cisco NX-OS fix in Cisco CSCwk49611 Delayed linkup seen with 100G-SR4 on BV ports
- CONTAP-292006: Network port on X1122A card, connected to Cisco Nexus 93240 Switch, does not come up when booting the node resolved by Cisco NX-OS fix in Cisco Bug: CSCvz66598 - N9K-FX3 10G/40G port bringup delay
Defects with pending fixes
- CONTAP-259740: Link goes down on XL710 Ethernet port when the node boots running ONTAP versions with fix for CONTAP-70312
- CONTAP-158568: NVIDIA CX6, CX6-DX, and CX7 Ethernet ports might fail to establish link to Cisco Nexus 9000 Series Switches related to Cisco Bug: CSCwm41191 - Interface not coming up when auto negotiation is enabled with QSFP-100G-PCC
