It is started at system startup. Q How to enable, disable or verify the vxconfigd daemon in Veritas Volume Manager? Ans : The vxbootsetup utility configures physical disks so that they can be used to boot the system.

These mirrors should be restricted mirrors of the volume. If medianame arguments are specified, only the named disks are configured. The swap volume is required to be named swapvol and to have a usage type of swap. Ans : The vxrootmir script creates mirrors of volumes required in booting.

It creates a mirror for rootvol, swapvol and standvol. It also creates mirrors of usr, var and home if they exist as separate volumes on the boot disk. The mirror is created on the specified disk media device. The specified disk media device should have enough space to contain the mirror for all the source volumes mentione above, or else it will fail.

Also, corresponding slices must be free because it is used to create the partition for root. This script is called by the vxmirror command if the root disk is required to be mirrored. It is also called from the vxdiskadm menus through the choice of the mirror volumes on a disk operation. Ans : The vxmirror command provides a mechanism to mirror all the contents of a specified disk, to mirror all currently un-mirrored volumes in the specified disk group, or to change or display the current defaults for mirroring.

All volumes that have only a single plex mirror copy , will be mirrored by adding an additional plex. It is not an interactive command and once called, will continue until completion of the operation or until a failure is detected.

Ans : The vxunroot script causes the root, swap, usr and var file systems to be converted back into being accessible directly through disk partitions instead of through volume devices. Other changes made to ensure the booting of the system from the root volume are also removed such that the system will boot with no dependency on the Volume Manager. For vxunroot to work properly, all but one plexes of rootvol, swapvol, usr and var should be removed.

The plexes left behind for the above volumes should be the ones created by vxrootmir or the original ones created when the root disk was encapsulated. This will ensure that the underlying subdisks will have equivalent partitions defined for them on the disk. If none of these conditions are met, the vxunroot operation will fail and none of the volumes will be converted to disk partitions.

These should be identical in size to those on the original root disk before encapsulation unless you are using this procedure to change their sizes. Ans : Reinstallation is necessary if all copies of your root disks are damaged, or if certain critical files are lost due to file system damage. Disconnect all the disks which are not involved in reinstallation process.

Now the configuration preserved on the disks not involved in the reinstallation has now been recovered. The preconvert utility analyzes the current Solaris Volume Manager configuration and builds a description for the new VxVM configuration. Note: The convertname utility takes Solaris Volume Manager device paths as arguments metadevice paths or raw disk paths and returns the VxVM volume path for the device as it will show after the conversion.

Ans : To remove a disk, disk90, from a disk group, homedg, in Veritas Volume Manager: vxdg -g homedg rmdisk disk90 Q -3 How to clear an import in Veritas Volume Manager after a crash? Ans : vxdisk list Q -5 How to remove a grayed out or obsolete disk, or remove a disk from a disk group in Veritas Volume Manager? Ans : vxdisk rm disk01 Q -6 How to remove a disk so that it is no longer under Veritas Volume Manager controls? Ans : To add or bring a disk under Veritas Volume Manager control: vxdiskadd c0t0d1 or vxdisksetup -i c0t0d1 Note: It might help to newfs the s2 slice of the disk and perform a vxdctl enable to get it to add a disk.

Ans : vxedit -g rootdg rename disk90 disk80 Q How to set disk90 in the group homedg to be a hot spare in Veritas Volume Manager? Ans : vxdg defaultdg Q -2 How to set the default disk group? Q How to split a disk group to form a new disk group? Q How to join two DGs into one? Q -3 How to create a plex from a subdisk in Veritas Volume Manager? Ans : To make a subdisk called subdisk at the beginning of the disk disk80 of size blocks: vxmake sd subdisk disk80,0, If you wanted to put another subdisk on this disk then you would have an offset of the size of the previous subdisk in our case : vxmake sd subdisk disk80,, Q -5 How to set a plex offline in Veritas Volume Manager?

I have a machine 5. I have the disk, it is labeled and ready but I am not sure of the next steps to mirror the existing diskgroup and Veritas volume manager in solaris. Can you please let me know the certification code for veritas volume manager in solaris? Thanks in advance. RAID manager or veritas volume manager. Can somebody kindly help me to determine which one i should choose to better manipulate OS volume. RAID manager or veritas volume manager?

Any critical differences between those two? Hello friends, I need to test some of the solaris 10 concepts and veritas volume manager. Thanks in Advance -Jay 6 Replies.
