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.

vxprint output description
Hi I am nwbie in vxvm, I want to understand a scenario,Kindly help me on this, a) In this vxprint o/p, what does these 4 plexes means.. which type of RAID configuration it is, if there are 2 plexes or 5 plexes what would be the RAID configuration. b) What is meant by DISKOFFS & LENGTH mentioned here.. in SD section. Does that size in 512-byte blocks or 1024-byte blocks? c) What is 0 denoted here after LENGTH in SD section?

Team, Just a small question, Server X and Y are in cluster with shared DG Suppose a server X shows appdg free space in 100GB and in Y server Disks are showing in deported state. Do the size of the appdg shows the same after importing it to Y server as 100 GB. Thanks..Solved612Views0likes1Comment
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 ?

Hi All, Arch=Sparc OS=Solaris 10 Release=3/05 Initial Release SFHA=VCS,VxVM,VxFS Version=4.1 I'm planning to upgrade Solaris host from Initial Release to Latest Release (Solaris 10 1/13 Update 11). Also the host is running VxVM,VxFS & VCS everything verson 4.1 After Solaris Upgrade to latest release will SFHA 4.1 work fine. Will VCS Service Groups come online and VxFS file systems get mounted while running 4.1 ? Kindly note that only for testing purpose i want to know this. Once Solaris is upgraded I will also upgrade SFHA to version 5.1SP1RP4 or to version 6. Reply is highly appreciated.
