VCS new volume created. Need to add up under existing Resource Group under 2 node clustered Solaris 10 Server...Important..please assist
Hi, I am newbi to VCS. OS is Solaris10. Two node cluster env. New filesystem already created and mounted with dedicated Vertual IP and is already under VCS. We have added two more Vol's (Vol03 & Vol04) in the existing Resource Group say 'node1_rg' Guys, please help me out to know the sequential and step by step procedure with commands to take the newly created Volumes under existing Resource Group......and how to carry out the Failover Test. this is a test server on which we need to do the task. Oracle Database is also there and we can coordinate with App & DBA team to do this activity...... Pleaseeeeeeee help. this is first time I had been to this forum seeking the help...

Hi All, I tried to bring a SG online in a node but it's not comming online. Let me explaing the issue. We did reboot of a node aixprd001 and we found that /etc/filesystem is corrupted so the SG bosinit_SG is in partial state since lot of cluster FS in not mounted. Then we corrected the entry and done the manual mout of all the FS but the SG still show the status partial so we did the bellow command. hagrp -clear bosinit_SG -all Once done the SG is in online state. For safer side we tried to offline the SG and brought it up online again but the SG failed to come online, Bellow is the only error we able find the engine_A.log file. 2014/12/17 06:49:04 VCS NOTICE V-16-1-10166 Initiating manual online of group bosinit_SG on system aixprd001 2014/12/17 06:49:04 VCS NOTICE V-16-1-10233 Clearing Restart attribute for group bosinit_SG on all nodes Please help me by providing suggestion, I will provide the output of logs if needed.

Hi All, We have recently built a 4-node Oracle single-instance CFS cluster, with more to on the way. The cluster will host many databases, and all nodes will be active. The databases will migrate from non-clustered to CFS clustered servers, and we are concerned about what effect CFS may have on performance. Concerns: - Suitability of our LLT links to handle intra-node communication generated by CFS ? - Location of CFS primary, for each filesytem, and how to determine if it is optimal ? - When multiple nodes write to the same filesystem simultaeously, would that be detrimental to performance ? - I am aware of GLM lock/release as one source of CFS intra-node traffic, but wondering if there are other significant sources, such as VxFS cache coherency ? - How to best monitor CFS overhead, intra-node traffic, and overall health ?

Folks, Any thoughts how does Oracle RAC handles Split Brain situation ? Might be this is a relative question with w.r.t two varied technologies .. but I assume its the best place to put this as Veritas is master in handling SPLIT BRAIN situation.

We have a slightly complicated question, it is, however, not really that complicated. We are moving one of our money generating apps over to dedicated UCS blades, and in VCS, (Linux on UCS blades with VCS), there is, however, some talk of using VMware and vMotion, and treat this application like other VM's that we have - in the sense, vMotion them in case of failover. This app has Terabytes of data. It is currently running on powerful Solaris systems and will be migrated to Linux on UCS. I sense that VMware is good for small databases and small apps..... My thinking is that changes should occur at higher levels, thereby insulating lower levels, given this logic, for instance, a failover should occur at the VCS level, not below the os....things like, if the os gets corrupted, vMotion will move the corrupted data alongwith. What do you recommend and why?1.1KViews0likes1CommentVVR with Geo-cluster Implementation.
Hello, We are planning to implement a DR solution using VVR for data replication and Geo-cluster for failover. The production side consists of 2 node cluster (2 ldoms) and the DR consist of 1 node cluster (1 ldom). On the production side we have 1 ldom per customer with a single VCSservice group for the customer,whereas some of of the ldoms have several customers in a single cluster with multiple service groups (1 service group per customer). We need the ability to failover a single customer to the DR site. In the case of single ldom or enviorment per customer we can do this easily. My query isin case ofmultiple customers/service groupson the single ldom and in a single VCS cluster, will this cause any limitation or is just case of failing over the service group for the particular customer.Solved985Views0likes2Comments
