Lvmtab file

First, create a directory with the desired name of your VG for example. After that using mknod command creates a special group file. In command, you need to supply major and minor numbers. This command has several options as below :. If not supplied then their respective values will be taken into consideration while creating VG. Changes in parameters with these options can be seen in vgdisplay output which you can see incoming section.

This file stores the bindings of physical volumes to their corresponsing volume groups. Thanks to all your answers, I renamed the lvmtab file and started a vgscan -v as suggested. Scan of Physical Volumes Complete. I plugged both power cables in both power supply. However, show faulty command shows below message.

Hi Guys, One of two disks in my solaris machine has failed, the name is disk0, this is SUN physical sparc machine But I work remotely, so people working near that physical server are not that technical, so from OS command prompt can run some command to bink faulty disk at front panel of Server Remove the disk online. My doubt is can I remove this hdisk2 online?

Can someone suggest if I can replace this disk online. Also how to check if there is some data present in hdisk2 alone They reported to us that one of the disks is faulty and they want us to take care of it. Below is Help with faulty Disk on Sun OS. Hi, Recently i came across a disk that seems to be faulty and need help. I have gathered some information by running below commands and any help on how to solve this will be great.

There is an faulty disk which is not part of an raid volume but shows fault in the diagnostics. Remove os mirrored disk Solaris How to remove disk from mirror? In this example, the total free space is physical extents of 4 MB, or MB. The logical volume is mirrored with a strict allocation policy, and there are not enough extents on a separate disk to comply with the allocation policy. To confirm this, run lvdisplay to determine which disks the logical volume occupies, and then check whether there is sufficient space on the other disks in the volume group.

In a SAN environment, one of the disks was dynamically increased in size. LVM did not detect the asynchronous change in size. Choose a smaller size for the logical volume, or add more disk space to the volume group.

Alternatively, free up space on an available disk using pvmove. Use the vgmodify command to detect the disk size change and incorporate the new space into the volume group. The boot disk firmware cannot access the entire range of the swap logical volume. This happens with older host bus adapters when primary swap is configured past 4 GB on the disk. Upgrade the system firmware or use a newer host bus adapter that supports block addressing. If neither of these actions succeeds, reduce the size of the primary swap logical volume so that it does not exceed 4 GB.

The specified path is not part of any volume group, because the path has not been successfully attached to the otherwise active volume group it belongs to. Check the specified path name to make sure it is correct. If the error occurred while detaching a physical volume, specify a different path.

If it is not clear whether any path was attached before, individually detach each path to the physical volume using pvchange with the —a n option. This warning is advisory. It is generated whenever a path or physical volume is detached. The LVM header on the disk is incorrect. This can happen when an existing LVM disk is overwritten with a command like dd or pvcreate.

If the disk is shared between two systems, one system might not be aware that the disk is already in a volume group. The corruption can also be caused by running vgchgid incorrectly when using BC split volumes. Restore a known good configuration to the disk using vgcfgrestore. Be sure to use a valid copy dated before the first occurrence of the problem. The vgcfgrestore command was used to initialize a disk that already belongs to an active volume group.

Detach the physical volume or deactivate the volume group before attempting to restore the physical volume. If the disk may be corrupted, detach the disk and mark it using vgcfgrestore , then attach it again without replacing the disk. This causes LVM to reinitialize the disk and synchronize any mirrored user data mapped there.
