Document Version Release Date Details 2 02-19-2021 The Resolution section has been updated with the firmware versions containing the solution. 1 12-02-2020 Original document release. On an HPE Virtual Connect SE 100Gb F32 Module for Synergy or an HPE Virtual Connect SE 40Gb F8 Module for Synergy, a segmentation fault crash may occur when collecting an LE support dump, whether via HPE OneView or manually. A certain Network Operating System service may stop responding when the "show running-config" command is executed by the support dump operation. This issue occurs only when over 100 server profile connections and uplinks/port channels are assigned to the same VLAN in the Logical Interconnect. As a result, loss of Network connectivity in the Logical Interconnect may occur, while Virtual Connect modules recover. When this issue occurs, the LE support dump will be missing certain log files. Due to a new feature included in HPE OneView 5.3 (or later), this issue has a higher probability of occurrence. As per the HPE OneView 5.3 release notes: "Provides enhanced customer experience by providing customers the ability to enable the re-usage of the same VLAN on neighbor vNICs at the same host. This feature provides the customer the ability to assign the same VLAN to multiple FlexNICs on the same port." More than two s-channels in a Server Profile can now be assigned to the same VLAN. Consequently, it will be easier to cross the threshold of 100 s-channels in a given VLAN in the Virtual Connect "show vlan" output. The following "show vlan" example (generated via netop CLI login) shows over 130 s-channels assigned to VLAN 41: Vlan ID : 41 Member Ports : po2, S-Channel0/1/7:2, S-Channel0/1/7:4, S-Channel0/1/1:2 S-Channel0/1/1:4, S-Channel0/1/8:2, S-Channel0/1/8:4, S-Channel0/1/2:2 S-Channel0/1/2:4, S-Channel0/1/9:2, S-Channel0/1/9:4, S-Channel0/1/3:2 S-Channel0/1/3:4, S-Channel0/1/10:2, S-Channel0/1/10:4, S-Channel0/1/4:2 S-Channel0/1/4:4, S-Channel0/1/11:2, S-Channel0/1/11:4, S-Channel0/1/5:2 S-Channel0/1/5:4, S-Channel0/1/12:2, S-Channel0/1/12:4, S-Channel0/1/6:4 S-Channel0/2/2:2, S-Channel0/2/2:4, S-Channel0/2/8:2, S-Channel0/2/8:4 S-Channel0/2/9:2, S-Channel0/2/9:4, S-Channel0/2/1:2, S-Channel0/2/1:4 S-Channel0/2/3:2, S-Channel0/2/3:4, S-Channel0/2/7:2, S-Channel0/2/7:4 S-Channel0/2/10:2, S-Channel0/2/10:4, S-Channel0/2/6:2, S-Channel0/2/6:4 S-Channel0/2/4:2, S-Channel0/2/4:4, S-Channel0/2/11:2, S-Channel0/2/11:4 S-Channel0/2/5:2, S-Channel0/2/5:4, S-Channel0/3/2:2, S-Channel0/3/2:4 S-Channel0/3/8:2, S-Channel0/3/8:4, S-Channel0/3/9:2, S-Channel0/3/9:4 S-Channel0/3/1:2, S-Channel0/3/1:4, S-Channel0/3/3:2, S-Channel0/3/3:4 S-Channel0/3/7:2, S-Channel0/3/7:4, S-Channel0/3/10:2, S-Channel0/3/10:4 S-Channel0/3/6:2, S-Channel0/3/6:4, S-Channel0/3/4:2, S-Channel0/3/4:4 S-Channel0/3/11:5, S-Channel0/3/5:2, S-Channel0/3/5:4, S-Channel1/2/1:2 S-Channel1/2/1:4, S-Channel1/2/7:2, S-Channel1/2/7:4, S-Channel1/2/2:2 S-Channel1/2/2:4, S-Channel1/2/8:2, S-Channel1/2/8:4, S-Channel1/2/3:2 S-Channel1/2/3:4, S-Channel1/2/9:2, S-Channel1/2/9:4, S-Channel1/2/4:2 S-Channel1/2/4:4, S-Channel1/2/10:2, S-Channel1/2/10:4, S-Channel1/2/5:2 S-Channel1/2/5:4, S-Channel1/2/11:2, S-Channel1/2/11:4, S-Channel1/2/6:2 S-Channel1/2/6:4, S-Channel1/1/8:2, S-Channel1/1/8:4, S-Channel1/1/2:2 S-Channel1/1/2:4, S-Channel1/1/3:2, S-Channel1/1/3:4, S-Channel1/1/7:2 S-Channel1/1/7:4, S-Channel1/1/9:2, S-Channel1/1/9:4, S-Channel1/1/1:2 S-Channel1/1/1:4, S-Channel1/1/4:2, S-Channel1/1/4:4, S-Channel1/1/12:2 S-Channel1/1/12:4, S-Channel1/1/10:2, S-Channel1/1/10:4, S-Channel1/1/6:4 S-Channel1/1/5:2, S-Channel1/1/5:4, S-Channel1/1/11:2, S-Channel1/1/11:4 S-Channel1/3/8:2, S-Channel1/3/8:4, S-Channel1/3/2:2, S-Channel1/3/2:4 S-Channel1/3/3:2, S-Channel1/3/3:4, S-Channel1/3/7:2, S-Channel1/3/7:4 S-Channel1/3/9:2, S-Channel1/3/9:4, S-Channel1/3/1:2, S-Channel1/3/1:4 S-Channel1/3/4:2, S-Channel1/3/4:4, S-Channel1/3/10:2, S-Channel1/3/10:4 S-Channel1/3/6:2, S-Channel1/3/6:4, S-Channel1/3/5:2, S-Channel1/3/5:4 S-Channel1/3/11:5 Untagged Ports : None Forbidden Ports : None Name : ce97a0d5a259407d9a8cda34a8e6cb8f Status : Permanent Egress Ethertype : 0x8100 Service Loopback Status : Disabled Private Network Status : Disabled
In the scenario described above, HPE OneView 5.3 (or later) with the following Virtual Connect modules: HPE Virtual Connect SE 100Gb F32 Module for Synergy HPE Virtual Connect SE 40Gb F8 Module for Synergy
This issue has been resolved in the following firmware versions: HPE Virtual Connect SE 100Gb F32 Module for Synergy firmware version 2.2.0-1003 (or later). HPE Virtual Connect SE 40Gb F8 Module for Synergy firmware version 1.7.0-1002 (or later). The above firmware versions can be found in the HPE Synergy Software Releases page. If this issue has occurred, either of the following workarounds are available: Configure the Ethernet connections and VLAN assignment to ensure that less than 100 s-channels will be assigned to a given VLAN. This may require creating separate Network sets (for example: production and management VLANs), instead of creating one large Network set and assigning it to all the Ethernet connections in the Server Profiles. OR Lower the number of Ethernet connections in the Server Profiles to only 2; especially if assigning every Network in the Logical Interconnect to every Ethernet connection via a Network set.
