Solaris, live migragtion on failover instead of stop/start of LDOMs
Hi all, I have the following setup: Solaris 11.3 SPARC LDM 3.3 VCS 7.1 3x SPARC T5-2 Servers 2x I/O domains per system From Visualization Guide about Failover scenarios: Domain state: Control domain Alternate I/O VCS behavior Up Up No fail over Up Down No fail over Down Up Fail over* Down Down Fail over** * VCS behavior would be “No fail over” with service group in auto-disabled state if the LDom resource attribute DomainFailurePolicy for the control domain is set to “ignore” and the LDom service group attribute SysDownPolicy is set to “AutoDisableNoOffline”. ** VCS behavior would be “No fail over” with service group in auto-disabled state if the LDom resource attribute DomainFailurePolicy for the control and other I/O domain is set to “ignore” and the LDom service group attribute SysDownPolicy is set to “AutoDisableNoOffline” So far so good, but VCS doesn't triggers the Live Migration, instead Logical Domain stops on one system and starts on another. Is here the possibility to change the behavior from stop/start to migrate? AFAIK, the Oracle (Sun) Cluster can do that afterclrs set -p Migration_type=MIGRATE ldom1-rs Thank you!
cfsmount1 &cfsmount2 resource could not offline
I met a problem about vcs. Environment: HW T5220 Server *2 + ax4-5; Problem description: When executing “init 6” or “hastop –all” command in cluster system, resource cfsmount1&cfsmount2 could not been offline normally; Checked with the HW state(EMC connective state ,disk, system, iostat –En),the output of “vxdisk , vxprint, vxdmpadm, fuser, mount –v etc.” I tried to umount /var/opt/mediation/MMStorage manually, it did not succeed and it look like the process has hung up; Please see check list in attach file check_point.log , engine_A.log and main.cf . Could you give me some advice about how to fix the problem?cfsmount1 &cfsmount2 resource could not offline

hi all. I'm using an application in a global cluster environment formed by 2 mini-cluster with one node each one, configured by a supplier. this application is using 2 NICs: one for the LAN of the management of the servers and one for the LAN of themanagement of the network elements. The supplier only configured a resource associated to the NIC of the management so, in case of a fault of this NIC the application can switch, while in case of a fault of the NIC of the network element the application freezes. This behaviour is obviously unacceptable, but the answer of the supplier was: the application doesn't support this feature (2 NIC resources together, apart from the heartbeat NIC). Is this possible ? I know that you cannot know how the application works, but I think that the configuration of the NIC resources is totally indipendent of the application itself, in whatever way it works. Is this correct ? thanks in advance and BR Tiziano
