vxvm troubleshooting - claim ownership of disk for new diskgroup

this is the issue

trying to add a disk to a diskgroup via vxdiskadm option 1 - the disk used to belong to a solaris host (this is emc symmetrix device)- and the disk is already owned by a diskgroup on the eupr0037 (now decommisoned) and I want to add it to eupr0201

when I do a vxdisk list cxtxtdx it shows the disk as owned by a dgprapdcd01 (a dg on the decommed eupr0037)

the solution is simple – run the following command

vxdisk –f init cxtxdx

and then run a vxdisk list cxtxdx and you will see diff ownership for the disk and no group assigned to it

you can then run a vxdiskadm > option 1 and readd the disk you want to the diskgroup you want

mount nfs mount and add it fstab in linux

example of how to mount an nfs mount

mount -t nfs eslat001:/opt/ims /app/ims
mount -t nfs eslat001:/opt/rims /app/rims


and then add to the /etc/fstab with the following entries;

servername:/pathofdir /pathonserver nfs options 0 0


where;

The corresponds to hostname, IP address, or fully qualified domain name of the server exporting the file system.

The is the path to the exported directory.

The specifies where on the local file system to mount the exported directory. This mount point must exist before /etc/fstab is read or the mount will fail.

The nfs option specifies the type of file system being mounted.

The area specifies mount options for the file system. For example, if the options area states rw,suid, the exported file system will be mounted read-write and the user and groupid set by the server will be used. Note that parentheses are not to be used here
