Each guest gets its network redundancy from all the fourI/O domains.Veritas Storage Foundation features restrictionsThe following Veritas Storage Foundation software features are restricted in theOracle VM Server for SPARC guest domain environment.Veritas Volume Replicator bunker replicationVeritas Volume Replicator (VVR) currently does not support configuring a guestdomain as a bunker node in the bunker replication mode. This restriction may beremoved in a later release.

Storage Foundation and High Availability Solutions support for Oracle VM Server for SPARCSystem requirements79Mirroring across controllers using vxassist the mirror=ctlroptionCurrently, all virtual disks in the guest are under the same virtual controller c0.When vxassist tries to look for a second controller to place the mirror on, it failsand therefore the command fails.All disks fall under the c0 controller, even if they are exported using differentphysical paths in the backend and coming from different HBAs.DMP SCSI bypassThe virtual disk client (VDC) driver controls all virtual disks in the guest domainand not the SCSI driver.Therefore, it is not possible to construct a SCSI packet and send the packet downthrough DMP. Setting the tunable dmp_fast_recovery to on has no effect.Event Source Daemon (vxesd) fabric monitoring capabilitiesOne of the features of the vxesd daemon is to register with the HBA API to listento fabric events. Even though the HBA API is loaded in the guest, since there iscurrently no concept of a directly connected HBA in the guest, this API is not ofany use. Therefore, this capability of vxesd is not available.Physical WWN for a pathSystem requirementsIt is not possible to create a Sub Path Failover Group (SFG) without Physical WWN.Physical World Wide IDs cannot be obtained from inside the guest because theyare fetched by DMP using the HBA API which is currently not functional insidethe guest.This section describes the system requirements for this release.Solaris operating system requirementsVeritas Storage Foundation for Oracle VM Server for SPARC is supported on thefollowing Solaris operating systems:■Solaris 10 (SPARC Platform) Update 7 or laterNote: Symantec recommends installing the latest Solaris 10 Update.
