Correction: Link drops are not for a few seconds but for 8 to 10 minutes all links are down. Extra info: This is our first ProLiant BL460c G7 blade and instead of the Broadcom chipset (ProLiant BL460c G6 series Ethernet controller: Broadcom Corporation NetXtreme II BCM57711E 10-Gigabit PCIe) it has an emulex NIC chipset eg Ethernet controller: Emulex Corporation OneConnect 10Gb NIC (be3) (rev 01) This is likely a duplicate of bug 671595. That bug will be fixed in RHEL5.7 and in RHEL5.6 errata kernel version 2.6.18-238.4.1.el5. Please test that kernel and reopen if it does not resolve the issue. Thanks! *** This bug has been marked as a duplicate of bug 671595 *** |
Description of problem: Due to configuration changes on HP Virtual Connect, sometimes the NIC links drops for a few seconds. This is not desirable but RHELS 6.0 systems in this Blade enclosure come back on-line without problems. This specific RH 5.6 system crashed with a kernel BUG and was rebooted by HP ASR because it hang after the crash. Version-Release number of selected component (if applicable): How reproducible: Hopefully not because last time I 'only' had to restart the networking service via the ILO console to enable networking again. This is the first time it actually crashed the system. Expected results: Detecting links down and up again without loosing network connectivity in the end or a complete system failure. Additional info: Manufacturer: HP Product Name: ProLiant BL460c G7 SKU Number: 603718-B21 Family: ProLiant ]# /var/log/messages Jan 31 13:49:00 scomp1101 kernel: bonding: bond0: link status definitely up for interface eth1.
