How do I verify my data size that will be replicated through VVR
I need to find a way to figure out the Mb/sec (Mb=Megabits) that will be replicated to my offsite and the pipe size I need in order to stay insync. I have been testing VVR and have all of my setting in place with everything working correctly. But with a 10Mb VPN internet pipe I have the line pegged at 10Mb all the time and am never able to catchup. When I looked at Performance monitor, Physical and Logical disks I am only generating about 4Mb/sec of disk writes which is what is being replicated the the offsite. Am I looking at the wrong data for my replication size needed? Is there a way to verify the Mb/sec that are going to be written the my offsite prior to starting VVR? NOTE: If you are having similar problems make sure to read the whole thread, there were mutliple solutions that were needed to verify and fix the problem of the data never catching up completely.Solved5.2KViews3likes17Comments
VVR has 2 primaries
I have successfully installed NBU on both nodes. Thanks for the help everyone. The only outstanding issue I now have is with the replication. If this needs to be a new post in a different section let me know! I have run the Volume Replicator Agent Configuration wizard successfully and my initial testing of failing between nodes went perfectly. However, at some point during the testing both nodes have ended up thinking that they are the primary in the GUI and I cannot see the secondaries listed,although everything looks correct in VCS and I can still bring everything online on each side with no errors. Something clearly isn't right with it though. I have tried deleting the RDS in the GUI and using commands to create it again, but it seems to be somewhat stuck and I can't seem to remove it or change anything now! Here's the output on what should be the primary node: C:\>vradmin -g NBUCATDG takeover nbuRVG Error occurred on host HOST1. Error V-106-58644-541: Primary takeover is not supported in present configuratio n. C:\>vradmin -g NBUCATDG stoprep nbuRVG HOST2 Error occurred on host HOST2. Error V-106-58644-528: Cannot complete operation. RDS is incomplete, either prim ary or secondary node is missing. C:\>vradmin -g NBUCATDG delsec nbuRVG HOST2 Error occurred on host HOST1. Error V-106-58644-513: This operation cannot be performed in present state of th e configuration. Please try again. C:\>vradmin -g NBUCATDG -f delpri nbuRVG Failed to perform the operation. Error V-106-58644-698: Operation not allowed. The RVG cluster resource is alread y configured for this RVG. Use -f option to forcefully stop it. C:\>vradmin -g NBUCATDG -f delrds nbuRDS Failed to perform the operation. Error V-107-58644-917: Cannot identify the correct RDS. C:\>vradmin -l printrvg Replicated Data Set : nbuRDS Primary : Hostname : HOST1 <localhost> RvgName : nbuRVG DgName : NBUCATDG Datavol_cnt : 1 Srl : vvrlog Rlinks: Name = rlk_primary ,rlink_state = ACTIVE, synchronous = override UPDATE: After switching back to what should be the secondary node (HOST2) I found that most of the above commands give a different error: "Error V-106-58644-697: Cannot perform this operation on an acting secondary RVG". Howeverin the VEAGUI it is listed as the primary.Solved2KViews1like2Comments
How to check VVR replication status
Hi, one of our customers is using storage foundation 6.0 for Windows and they use VVR to replicate volumes from production site to dr site. The replication is in asynchronous mode. My question is: How to check VVR replication status? Is there a way to show the replication progress such as how many percentages have been replicated and/or how long it takes to complete the replication? Thanks in advance.Solved5.2KViews1like2Comments
VERITAS VOLUME REPLICATION DCM LOG INCREASING
Hi, I have volume replicated two servers one is in myDC& another in DR in different geographic location. As due to some technical falult the DR server was not reachable for 2 days so replication hampered. After the DR server is up but till date the DCM log is gradually increasing day by day. Can anyone help me in rectify this, if I have to do DC - DR drill is it possible or feasable to do that till the logs cleared. Please help. Thanks in advance.2.2KViews1like1Comment
