Disk group not imported
SFHA 5.1 SP2 , Win2008 64-bit, with sql2008 and disaster recovery configuration with global cluster manager The point is that due to unknown disk error during evacuating a cluster disk, a cluster disk group in the recovery site cannot be imported because of missing volumes. Is there a way of solving this (eg. force import the disk group, and reconfigure vvr rvg group) , or do i have to reconfigure this cluster disk group (VVR and so on) from the beginning ? Thanks in advancedVVR Block Pending Status
Hi, Professional I would like to get the answer and solution with this detail. My customer using VVR 3.3 on windows 2003 and all service all fine but there are lag of blocks change between primary and second but I'm new in this product and I have no idea to determine which is the main cuase of the issue, please suugest me. What can probaby occur with is system. Thank you.Poor disk write performance
We have a server 2003 R2 machine, which primarily is running as our NetBackup Master server. In addition to this we have a second machine which is/was setup as in a cluster using Veritas Storage Foundations VVR to replicate the data and VCS to handle the application side of things. About three weeks ago we noticed that the disk write performance was very bad. Using a tool provided by NetBackup to write zero's to the file systems, we noted that it would start off fast, and then performance would drop significantly to the point where it was writing about 0Mb/s or 1Mb/s. This is present on both SAN volumes and local volumes. The same write profile is observed. We also see disk queue lengths go up to 130, but no higher than this This is the case on both of the servers running VCS/VSF, but is not present on any other servers running NBU but not running the storage foundation software. There is no VxCache memory config enabled on the server or any disks. All the disks are reporting as being misaligned. Some time ago VVR was disabled/broken and has not been reinstated as we do not have Symantec support on the product, and noone here knows how to use it. So I am reaching out to anyone who may be able to point me in the right direction. I have read the admin guide and it has given me a bit more understanding of the components in the software, but has not provided much in the way of troubleshooting this write performance problem. Today I will run IOMeter to test reads/writes and a combination of both. VSC/VSF version is 5.1 SP1
