Operating Systems Linux Red Hat Identify SAN disks not in use Post 302526356 by asanchez on Tuesday 31st of May 2011 09:53:39 AM

Well, we're managing around 1200 servers with a variety of unix-like OS (rhel, suse, centos, ibm aix, sunos and hp-ux).

And there are some with LVM, some with VxVM and some with none (fs's mounted directly to fdisk /dev/sdX partitions).

There is also multipathing with some systems.

To not make it more difficult, I'm trying to resolve it first in the RHEL case (LVM, VxVM and none).

NAME
dgcfgbackup - create or update VxVM volume group configuration backup file SYNOPSIS
/usr/sbin/dgcfgbackup [-f dg_conf_path ] dg_name DESCRIPTION
The dgcfgbackup command saves the VxVM configuration for a disk group in a default or alternate configuration backup file (see the descrip- tion of the-f option). By default, dgcfgbackup is run automatically each time that a VxVM command changes the VxVM configuration. In this case, it always uses the default configuration backup file. An existing default configuration backup file is renamed with an extension of .old. Options and Arguments dg_name Specifies the name of a disk group. -f dg_conf_path Saves the configuration using an alternate file name specified by dg_conf_path. If this option is omitted, the default file name is /etc/vxvmconf/dg_name.conf. EXIT CODES
dgcfgbackup exits with a zero status on successful completion. An non-zero exit status indicates that errors occurred when information from the disk group was being accessed. EXAMPLES
Back up VxVM configuration information for disk group testdg in the default backup file /etc/vxvmconf/testdg.conf: dgcfgbackup testdg Back up VxVM configuration information for disk group datadg in the alternate configuration backup file /tmp/datadg.backup: dgcfgbackup -f /tmp/datadg.backup datadg NOTES
It is recommended that any alternate configuration backup file be created in the root file system (as is the case with the default path name). This facilitates disk group recovery during maintenance mode, such as after a system crash. AUTHOR
dgcfgbackup was developed by the Hewlett-Packard Company. SEE ALSO
