VCS stop and service group offline quesiton
I have a quick question regarding service group offline. We only want to bring up/down services when we execute hagrp -online/-offline manually. When VCS shutdown, we don't want to bring up the service offline. I know if we freeze it won't go to offline entry. Do we have any other option? For an exmaple, for only we can disable the autostart. Do we have any thing for offline?Solved3.5KViews0likes2Comments
Doubts on VxVM,VCS Upgrade & root disk encapsulation
Hi All, I have the below queries please 1) In order to stop VxVM to load at system boot time, we need to modify /etc/system file. What entries are to be commented out ? Is it only rootdev:/pseudo/vxio@0:0 set vxio:vol_rootdev_is_volume=1 (OR) also below entries are to be commented out ? forceload: drv/vxdmp forceload: drv/vxio forceload: drv/vxspec 2) My current version of SFHA is 4.1. Once vxfen, gab & llt modules are unloaded to upgrade to 4.1MP2, should i again unload these modules to further upgrade to 5.1SP1 and again to 5.1SP1RP4 (OR) 6.0 ? After each upgrade should i stop the services in /etc/init.d and unload modules (OR) stopping services & unloading modules only once is enough to further upgrade to other versions ? My Plan is to upgrade from 4.1---> 4.1 MP2---> 5.1SP1--->5.1SP1RP4 (OR) 6.0 3) Before upgrading should i also stop & unload the below listed modules 24 12800a8 26920 268 1 vxdmp (VxVM 4.1z: DMP Driver) 25 7be00000 2115c8 269 1 vxio (VxVM 4.1z I/O driver) 27 12a4698 13f0 270 1 vxspec (VxVM 4.1z control/status driver) 213 7b2d7528 c40 272 1 vxportal (VxFS 4.1_REV-4.1B18_sol_GA_s10b) 214 7ae00000 1706a8 20 1 vxfs (VxFS 4.1_REV-4.1B18_sol_GA_s10b) If yes, should i stop & unload after each upgrade (OR) doing it once is enough ? 4) Once the OS comes up with native disks (c#t#d#s#), In order to bring it under VxVM control we need to encapsulate using vxdiskadm. My doubt is will rootdg, rootvol, plexes & subdisks be created automatically? Need a little clarification regarding this please. Response is highly appreciated as always, Thank you very much.

Continuity after a failover
Hi, I am new to clustering. 1. If I create a cluster with 2 nodes and shared storage, and keep my application running on node1, client applications will be connecting to my application on node1. In the event of a failover, when the application starts on node2, will the client applications need to change the IP address to which they were connecting? Or will VCS show a single IP address to the external world so that client applications do not need to be reconfigured? 2. Can I configure VCS to start my application on node2 automatically in the event of failover, without any manual intervention?
