Cisco Bug: CSCvv07141 - gISO label can be lost in specific RPFO/RP OIR scenarios
Jul 31, 2020
- Cisco ASR 9000 Series Aggregation Services Routers
Known Affected Releases
7.0.14.BASE 7.2.1.BASE 7.3.1.BASE
Symptom: On a dual RP system, the gISO label is lost from 'show version' following specific sequences of install operations and OIR events. To see if the gISO label could be lost following an RPFO, check the following files on the standby RP. 1) /pkg/etc/giso_label.txt should contain the gISO label 2) /etc/opt/cisco/iosxr/dhcp/server/install.conf should have an entry of the following form: option cisco-iosxr-install-giso-label "GISO_LABEL"; Conditions: Either: - System with no gISO label present, no standby or standby not booted - 'Install replace' to an image with a gISO label - Standby card inserted, with no version change required (eg, removed from a previous system at the same version as the active or powered off when at the same version). - RPFO OR - 'Install replace' operation changes the gISO label but does not require reload or install infra restart. (For example, the replace operation only includes bugfixes and none of them are for the install infra). - RPFO occurs twice (without any other label-impacting install operations inbetween).
