92About Veritas Storage Foundation and High Availability SolutionsKnown issuesshutdown on Solaris 11. If NIC monitor is invoked during this window, NIC agentmay treat this as fault.Workaround: Increase ToleranceLimit for NIC resource when it is configured forexclusive IP zone.Share resource goes offline unexpectedly causing service group failover[1939398]Share resource goes offline unexpectedly and causes a failover when NFSRestartresource goes offline and UseSMF attribute is set to 1 (one).When NFSRestart resource goes offline, NFS daemons are stopped. When UseSMFattribute is set to 1, the exported file systems become unavailable, hence Shareresource unexpectedly goes offline.Workaround: Set the value of ToleranceLimit of Share resource to a value morethan 1.Mount agent does not support all scenarios of loopback mountsFor a mount point under VCS control, you can create loop back mounts for themount point. For example, mount point /mntpt is mounted on /a as loop backmount and /a is mounted on /b as loop back mount, then offline and online of themount resource fails.Workaround: Mount the mount point /mntpt on /b as loop back mount.NFS client reports I/O error because of network split brain [2564517]When network split brain occurs, the failing node may take some time to panic.Thus, the service group on the failover node may fail to come online, as some ofthe resources (like IP resource) are still online on the failing node or disk groupon the failing node may get disabled but IP resource on the same node continuesto be online.
