Migrate ApplicationHA to new vCenter server
We're consolidating a number of vCenter servers into a single instance. One of the clusters we want to move has VMs managed by AppHA 6.0.1. Is there an easy way to migrate the cluster configuration from the old vCenter server to the new one without causing any cluster outages or losing the cluster configuration? I've found this article on how to deal with the permanent loss of a vCenter server, but an unsure what might happen if the existing vCenter server stays online. https://sort.symantec.com/public/documents/appha/6.0/windows/productguides/html/appha_userguide_60_win/apas11.htmSolved8.6KViews0likes9Comments

Requirements for my Master Server (RAM memory and processors)
Hi all. I have great doubt I am implementing a new platform in which there are 15 clients (Sun X4270). the questions is: The master server with netbackup to manage clients, that memory (RAM) should have? the ram of the master server depends on the clients? And talking about processors, also depends on customer? Obviously already taking into account the necessities of the installed applications Thank you and good daySolved6KViews1like9Comments

IP agent for same mac address interface
Hi all, Our environment as the following: OS: redhat 6.5 VCS: VCS 6.2.1 Our server have two physical network port, namely eth0 and eth1. We do create tagged vlan, vlan515, vlan516, vlan518, vlan520 based on eth0 and eth1. We are able to create resource IP on vlan518 and failover between two nodes. However, when we create resource IP on vlan515, it is not able to bring it online. According to the link, https://support.symantec.com/en_US/article.TECH214469.html, It knows that duplicate mac address would cause the problem. However, it can't figure out where "MACAddress" attribute in VCS Java Console as mentioned in the solution. I did manually add "MACAddress" attribute on main.cf on either NIC or IP resource, it come with not support with haconf -verify command. Any hints or solution for the problem when configure the IP agent resource on same mac address? Thanks, XentarSolved5.6KViews0likes22Comments
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.5.5KViews0likes8Comments
How to recover from failed attempt to switch to a different node in cluster
Hello everyone. I have a two node cluster to serve as an Oracle database server. I have the Oracle binaries installed on disks local to each of the nodes (so they are outside the control of the Cluster Manager). I have a diskgroup which is three 1TB LUNs from my SAN, six volumes on the diskgroup (u02 through u07), six mount points (/u02 through /u07), a database listener and the actual Oracle database. I was able to successfully manually bring up these individual components and confirmed that the database was up an running. I then tried a "Switch To" operation to see if everything would mode to the other node of the cluster. It turns out this was a bad idea. Within the Cluster Manager gui, the diskgroup has a state of Online, Istate of "Waiting to go offline propogate" and Flag of "Unable to offline". The volumes show as "Offline on all systems" but the mounts still show as online with "Status Unknown". When I try to take the mount points offline, I get the message "VCS ERROR V-16-1-10277 The Service Group i1025prd to which Resource Mnt_scratch belongs has failed or switch, online, and offline operations are prohibited." Can anyone tell me how I can fix this? KenSolved5KViews1like17CommentsSF4.1 VxDMP disables dmpnode on single path failure
This is more like an informational question, since I do not assume anyone has a solution, but just in case I would be thankfull for some enlightment: I am forced to use an old Version SF4.1MP4 in this case on Linux SLES9. For whatever reason DMP does not work with the JBOD I have added. The JBOD (Promise VTrak 610fD) is ALUA, so half of all the available paths are always standy and that is ok. But the DMP in 4.1 when seeing one of 4 paths not working diables the whole DMP Node, rendering the disk unusable: Jun 12 15:35:01 kernel: VxVM vxdmp V-5-0-148 i/o error occured on path 8/0x70 belonging to dmpnode 201/0x10<5>VxVM vxdmp V-5-0-148 i/o error anal ysis done on path 8/0x70 belonging to dmpnode 201/0x10<5>VxVM vxdmp V-5-0-0 SCSI error opcode=0x28 returned status=0x1 key=0x2 asc=0x4 ascq=0xb on path 8/0x70 Jun 12 15:35:01 kernel: VxVM vxdmp V-5-0-112 disabled path 8/0x50 belonging to the dmpnode 201/0x10 Jun 12 15:35:01 kernel: VxVM vxdmp V-5-0-112 disabled path 8/0x70 belonging to the dmpnode 201/0x10 Jun 12 15:35:01 kernel: VxVM vxdmp V-5-0-112 disabled path 8/0x10 belonging to the dmpnode 201/0x10 Jun 12 15:35:01 kernel: VxVM vxdmp V-5-0-112 disabled path 8/0x30 belonging to the dmpnode 201/0x10 Jun 12 15:35:01 kernel: VxVM vxdmp V-5-0-111 disabled dmpnode 201/0x10 Jun 12 15:35:01 kernel: Buffer I/O error on device VxDMP2, logical block 0 Currently my only solutions seems to stick with Linux DM-Multipathing an add the disks as foreign devices.SolvedDMP, MPIO, MSDSM, SCSI-3 and ALUA configuration settings
Ok, I'm somewhat confused and the more I read the more confused I think I'm getting. I'm going to be setting up a 4 node active/active cluster for SQL. All of the nodes will have 2 seperate fiber channel HBAs connecting through 2 seperate switches to our NetApp. The NetApp supports ALUA, so the storage guy wants to use it. It is my understanding that I need to use SCSI-3 to get this to work. Sounds good to me so far. My question is, do I need to use any of Microsoft's MPIO or MSDSM? This is on Win 2008 R2. Or does Veritas take care of all of that? Also, I read that in a new cluster set up, only connect 1 path first and then install and then connect the 2nd path and let Veritas detect it and configure it. Is that accurate? Any info or directions you can point me will be greatly appreciated. Thanks!Solved
