bulk transfer?? block size??
About bulk transfer with secondary logging To effectively use network bandwidth for replication, data is replicated to a disaster recovery (DR) site in bulk at 256 KB. This bulk data transfer reduces VVR CPU overhead and increases the overall replication throughput. With compression enabled, bulk data transfer improves the compression ratio and reduces the primary side CPU usage. question 1.Smaller than 256k did before? 2.Did you send compressed 256k?Solved2.9KViews0likes1Comment
The behavior of CVM/VxDMP
Hi, In the Release Notes of SF5.1, there is a statement "When all of the Primary paths fail or are disabled in a non-Active/Active array in a CVM cluster, the cluster-wide failover is triggered. All hosts in the cluster start using the Secondary path to the array." What do you think "all of the Primary paths" means? It means "all of the Primary paths of the master node" or means "all of the Primary paths of all nodes"? Below is the Release Notes: http://sfdoccentral.symantec.com/sf/5.1/solaris/html/sfcfs_notes/ch01s06s02s01.htm Thanks, Yu junMissing VCS "VVRTypes.cf"Agents
Need help/ advice on how to recover missing VVRTypes.cf System Info OS RHEL 6.1 VCS Version 5.1 rp3 Objective To enable VVR in VCS-GCO environment During the process of creating RVG for VVR Service Group; I found that Done the following Checks (i) VVRTypes.cf is MISSING from the /etc/VRTSvcs/conf/config directory (ii) /etc/VRTSvcs/conf/sample_vvr/addVVRTypes.sh is NOT there (iii) re-install VCS5.1-rp3 patch DOESNT work .

A path is a connection between the server/host computer and the storage array’s disks and consists of a host adapter and a SCSI bus connection to one or more SCSI disks or a fiber optic channel connected to a hub, switch, or array. Thus, multiple paths are made possible by connecting two or more host bus adapters with either SCSI or fiber optic cabling to the storage array. DMPW manages the multiple paths so that the data on each of the array’s disks is accessible to the host computer. If a path to a disk fails, Dynamic Multi-Pathing automatically transmits data to and from the disk over an alternate path. The paths on an array are set up to work in two ways—either in Active/Active mode, which provides load balancing of the data between multiple paths, or in Active/Passive mode, in which only one path is active and any remaining paths are backups. DMPW is implemented through Veritas Dynamic Multi-Pathing for Windows Device Specific Modules (DMPW DSMs). DMP DSMs are designed to support a multipath disk storage environment set up with the Microsoft Multipath I/O (MPIO) solution. DMP DSMs work effectively with Windows to provide a fault tolerant multipath disk storage environment.

Hello, I am evaluating AppllicationHA in my environment which is composed of LPARs in two frames installed in two separate sites. The LPARs are accesing two EMC storage VMAX and there is a replication link using SRDF. We are not able to use Live Partition Mobility between the two PowerSystem Servers because there is not an storage shared betweem them. For this reason we will like to use a VCS management cluster installed in the frames (one node on each PowerSystem Server) and this VCS cluster is using SRDF replication agent. My question is if we configure applicationHA in this VCS management cluster to protect a LPAR, can this LPAR use the VCS with SRDF agent? Doing so, we will solve our limitation and we will be able to relocate the LPAR to the other frame automatically. Thanks and best regards Osvaldo1.5KViews2likes1Comment
Can ApplicationHA 6.0 monitor multiple applications?
The forum had a similar question for the 5.1 release that indicated that multi app monitoring was coming (perhaps) in a future release, so I thought I'd pose the question again relative to the 6.0 release. Any change in status?Solved1.1KViews0likes3Comments
