Create second RDS using volumes from same disk group in Veritas volume replicator
Hi all, I have one query. I have one disk group with 5 volumes, which are more than 2 TB and are configured for replication. Now i want to add 2 more volumes in the RDS but it will resync all the volumes after adding these 2 volumes, so is it possible to make second RDS for only those 2 new volumes. Also can we use same IP for replication.
dcm resynchronization does not start automatically
Hi all: I am testing the vcs/vvr cluster . When I write a data which size exceeds the srl volume size, VVR goes to "logging to dcm" state. # vradmin -g data_dg -l repstatus rvg_b Replicated Data Set: rvg_b Primary: Host name: 192.168.100.111 RVG name: rvg_b DG name: data_dg RVG state: enabled for I/O Data volumes: 1 VSets: 0 SRL name: srl_b SRL size: 150.00 M Total secondaries: 1 Secondary: Host name: 192.168.100.112 RVG name: rvg_b DG name: data_dg Rlink from Primary: rlk_192.168.100.112_rvg_b Rlink to Primary: rlk_192.168.100.111_rvg_b Configured mode: asynchronous Latency protection: off SRL protection: autodcm Data status: consistent, behind Replication status: logging to DCM (needs dcm resynchronization) Current mode: asynchronous Logging to: DCM (contains 5572672 Kbytes) (SRL protection logging) Timestamp Information: N/A Bandwidth Limit: 100.00 Mbps Compression Mode: On After writing, the vvr keeps in "needs dcm resync" status and the resynchronization does not start automatically. What should I set to let the resync start auto? Btw:another question. If a new write operation on block operation coming in when the block is in dcm resync state, is the write action blocked or not?diskgroup does not start on secondary host
HI All: I configure a single vcs cluster with vvr. I save the configuration on the following pictures As you see on these pictures, I configure a service named apache2 using the RVGPrimary of vvrgroup, and set the relation between two service groups with command: >hagrp -link apache2 vvrgrp online local hard All the service group and resource take online successfully. But on the secondary node of VVR, the disk group is exported and the replication does not occur. vcs2:/var/VRTSvcs/log # vradmin -g data_dg repstatus rvg_b Replicated Data Set: rvg_b Primary: Host name: 192.168.100.112 RVG name: rvg_b DG name: data_dg RVG state: enabled for I/O Data volumes: 1 VSets: 0 SRL name: srl_b SRL size: 1.00 G Total secondaries: 1 Config Errors: 192.168.100.111: disk group missing Is there anything wrong in my configuration ? >cat main.cf include "OracleASMTypes.cf" include "types.cf" include "Db2udbTypes.cf" include "OracleTypes.cf" include "SybaseTypes.cf" cluster vcs ( UserNames = { admin = aHGcEBdBGeFBgJHbHFgGIg } ClusterAddress = "192.168.4.100" Administrators = { admin } ) system vcs1 ( ) system vcs2 ( ) group ClusterService ( SystemList = { vcs1 = 0, vcs2 = 1 } AutoStartList = { vcs1, vcs2 } OnlineRetryLimit = 3 OnlineRetryInterval = 120 ) IP webip ( Device = eth0 Address = "192.168.4.100" NetMask = "255.255.255.0" ) NIC csgnic ( Device = eth0 ) webip requires csgnic // resource dependency tree // // group ClusterService // { // IP webip // { // NIC csgnic // } // } group apache2 ( SystemList = { vcs1 = 0, vcs2 = 1 } ) Application httpd2 ( StartProgram = "/etc/init.d/apache2 start" StopProgram = "/etc/init.d/apache2 stop" PidFiles = { "/var/run/httpd2.pid" } ) IP ip_res ( Device = eth0 Address = "192.168.4.200" NetMask = "255.255.255.0" ) Mount appmount ( MountPoint = "/srv/www/htdocs" BlockDevice = "/dev/vx/dsk/data_dg/data_volume" FSType = vxfs FsckOpt = "-n" ) RVGPrimary DataRVG_pri ( RvgResourceName = DataRVG ) requires group vvrgrp online local hard appmount requires DataRVG_pri httpd2 requires appmount httpd2 requires ip_res // resource dependency tree // // group apache2 // { // Application httpd2 // { // IP ip_res // Mount appmount // { // RVGPrimary DataRVG_pri // } // } // } group vvrgrp ( SystemList = { vcs1 = 0, vcs2 = 1 } AutoStartList = { vcs1, vcs2 } ) DiskGroup DataDG ( DiskGroup = data_dg ) NIC vvrnic ( Device = eth1 ) RVG DataRVG ( RVG = rvg_b DiskGroup = data_dg ) DataRVG requires DataDG DataRVG requires vvrnic // resource dependency tree // // group vvrgrp // { // RVG DataRVG // { // DiskGroup DataDG // NIC vvrnic // } // }
Question about VxVM and VVR over AIX HACMP?
Hi, I'm trying to figure out what's steps are necesary to acomplish this: I have a Customer with two datacenters located far from each other, they have theirs primary datacenter with a two AIX Power7 SI -HACMP / GPFS / ORACLE RAC / CLUSTER by the Oracle RAC; they want to replicate this date with VVR to a secondary site with same configuration; the primary site is running at this time and We want to create minimal disturbance in the current environment and help them to replicate the ORacle data to the secondary site with VVR. Can We get control of these disk at the primary site with VxVM without any consideration or the customer have to put additional space and transfer current data to the new VxVM volumens? Thay have to modify additional things inside de HACMP to work with ours VxVM? They need to control de VVR replication at the command line or SMIT? The HACMP is aware of VVR or not? They have AIX 6.1, Oracle 10G, IBM DS5000 FC Storage boxes and 10MB (100Mbps) it's the bandwith of the replication channel? Thanks for your help, Best Regards, Gonzalo Gomez
