shutdown and restart Cluster with VEA
Hi all, I have to shutdown our Hardware for a while. Now I'm looking for the best way to do that. I have two storage SAN's connected to two hardware micosoft clusternodes(Windows Server 2003) with VEA 3.2. I will shutdown the sytsems this way: 1. passive Cluster node 2. aktiv cluster node 3. first san controller 4. second san controller 5. both storage's 6. FB switche and the restart this way: 1. FB switche 2. both storage's 3. both storage san controller 4. both cluster node's Are there any things i have to regard? Do the VEA start the to resync after the restart for hours? or it will only reconnect. I hope you can help me. Thank you!1.8KViews0likes3Comments

Enable Deduplication on NetBackup 7.5
Hi, We have got NetBackup 7.5.0.6 running on Windows Server 2008 and currently backing up data on SAN Storage. I want to enable deduplication on it. Couldyou please provide me the best practice procedure to do so ? Where the deduplication should be enabled on client or Server level and how it will be reflected on SAN storage? Please adivse Regards, --Tarek--1.5KViews0likes1CommentCalculate vxfs millisecond delay
We have a Netbackup master server cluster, the catalog/DB is sitting on a vxfs volume. There is a case open currently with Veritas and they have found massive delays (40 seconds!) at backup peak timeon the Sybase database and have recommended we do a "nbdb_unload -rebuild" and "nbdb_admin -reorganize". Meanwhile, we are looking at the IO on the catalog/DB volume. The technote below says the response shouldn't be more than 20ms. How do I determine the current response time, is there a Storage Foundation tool that can provide this? Our host is running RHEL6.6.Solved1.3KViews0likes2Comments
Change the Host IP address in the Veritas cluster
Hello All, We have a Veritas cluster server setup (VCS-HA,VCS-CFS & VERITAS-RAC) where on few setup we required to change the data IP address of some host(node). I refer few notes but not sure except /etc/hosts is there any file need to update/edit. Please help me if you have any process/technote to make those change & make that changed IP persistant. Also would like to know the impact of this activity. The systems are Linux 6.5 & 6.6 & cluster versions are VCS 6.2 & 6.1.Solved3.7KViews0likes3Comments
Disk space reporting
I'm runing VCS 5.0 and have a SG with NFS shares off a RAID from the two servers in my cluster. The problem I'm running into is a conflict ofhow muchdisk space is being used with a"df" compared to a "du". One of the file systems is off by 36GB. We've unshared the file system, took down the cluster, and tried an fsck, but no errors were reported and no changes to space being reported as a result. Has anyone ever seen this before?Solved1.1KViews0likes4Comments
Veritas Storage Foundation - Volume Disabled After 'rmdisk'
Dear All, I added a LUN to a specific volume and realised that I added it to the wrong volume. To remove the LUN the following command was run : "vxdg -g dg rmdisk vsp-xx-xx" I was then prompted to run the " -k" option to remove the disk. However after re-running the command with the " -k" option : "vxdg -g dg -k rmdisk vsp-xx-xx" ... the volume went into a disabled state. Fortunately no data was lost once the "vxmend" was completed on the volume. I would just like to know if this was to be expected when running the above with the " -k" option ?

CFS Health Check ?
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 ? Thank your for reading !

Unable to bring the Service Group online.
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.
