If there is any LVM header information on this disk, it must be removed prior to proceeding with any VxVM functions on the disk.
We want to use VxVM to perform various storage management functions on disk c2t2d0. The root disk under LVM control is c1t2d0. This output shows two internal disks and a CD-ROM drive (we'll later add two more disks to demonstrate a setup of mirroring and striping).

Two that contain much more detailed information on configuring and using VxVM are HP VERITAS Volume Manager Release Notes and HP VERITAS Volume Manager Administrator's Guide.
Root mirroring in veritas volume manager manuals#
Please see docs.hp.com for a complete list of manuals on VxVm. This is a product that has a lot of functionality and manuals devoted to using it, so in this part of the chapter we'll cover some of the basics. In the upcoming sections, we'll load HP Veritas Volume Manager and perform some basic storage management tasks so you can get a feel for this product. The root disk will remain under LVM control and not be placed under VxVM control. On the system used for the examples compiled for the VxVM part of this chapter the root disk setup at the time 11i was originally loaded on the system was under control of Logical Volume Manager (LVM.) After loading HP Veritas Volume Manager as an application we can then perform storage administration on other disks on the system. The features of each are described in the HP VERITAS Volume Manager Release Notes.
Root mirroring in veritas volume manager full version#
The full version performs all of the functions in the Base product and also supports load balancing, hot relocation and unrelocation, mirroring of up to 32 copies (RAID 1), mirrored stripes, striped mirrors, RAID 5, online migration, and online relayout.
With both versions of VxVM there is a Java-based administration interface, striping (RAID 0), concatenation, path failover support, online resizing of volumes, and a task monitor.
The Base product is a subset of the full version. There is a version of VxVM bundled with 11i called Base HP VERITAS Volume Manager and a full version called HP VERITAS Volume Manager.

The second link you've mentioned (TECH71339 ) would work, as it's effectively a cut-down version of the steps from TECH157465 - however TECH157465 mentions various other steps/considerations/precautions that might be relevant for your environment, and it also has the steps required to reencapsulate once you've booted from the disk / fixed the password issue.At the time of this writing, HP Veritas Volume Manager (what I'll call VxVM throughout much of this chapter) is a software product loaded from the HP-UX 11i Application CD-ROM. Ie: avoid doing this, likelihood of messing up the configuration is high unless you are very familiar with what you're doing, which does not appear to be the case. The system will break out of boot as it won't be able to access the /dev/vx devices it may let you modify the files, but depending on how far it gets through it may not and/or may cause other issues as it's an interrupted boot rather than a clean boot to single user. The steps in the first link ( ) won't work, as it only touches install-db - as Mike pointed out, it neglects the required modifications to system and vfstab. Please provide the well tested and standard procedure for my environment. root password is blank so just press ENTER to login. remove root password by removing the data between 1st and 2nd collon for root username.ġ2.
