Resizing Veritas volumes with vxresize

We were getting close to running out of space on one of our database volumes last week, and I needed to add some additional storage to ensure that things kept running smoothly. The admin who originally created the VxVM database volume only used half of each of the five disks that were associated with the […]

Removing duplicate devices from vxdisk list

I replaced a disk in one of our A5200s last week, and noticed that vxdisk was displaying two entries for the device once I replaced it with vxdiskadm: $ vxdisk list DEVICE TYPE DISK GROUP STATUS c7t21d0s2 sliced disk01 oradg online c7t22d0s2 sliced disk02 oradg error c7t22d0s2 sliced – - error c7t23d0s2 sliced disk03 oradg […]

Recreating Veritas configurations with vxmake

In the article I described how to backup a Veritas configuration to a file with vxconfigbackup, and how to restore it with vxconfigrestore. One thing I didn’t touch on was selectively restoring individual volume configurations. This is easy to do, […]

Tracing vxassist activity

While creating a few Veritas volumes last week, I wanted to see the commands that vxassist was executing under the covers. This was easily accomplished by adding the “-v” (trace commands executed by vxassist) option to the vxassist command line: $ vxassist -b -v make datavol02 1g layout=mirror mirror=3 /usr/sbin/vxvol -g datadg -o bg -o […]

Using Veritas Volume Manager with RHAS 4.0

I have used Veritas Volume Manager (VxVM) and Veritas File system (VxFS) for as long as I can remember. All of my VxVM and VxFS experience has been on Solaris, so I thought I would install both products on a Linux host to see if anything was different. The Linux installation turned out to be […]

Creating a Veritas Volume Manager volume from a plex

While cleaning up my Veritas VxVM notes this week, I came across one of my cheat sheets for creating volumes from plexes. This can be useful when you want to perform an offline backup of the data on an alternate server, or when you want to grab a spare copy of data prior to performing […]
