Backup for HW Mirrored Disks

Another reason that made change to raidctl is using and implementing LDoms. I found it a bit complicated maintaining the server with SVM and LDoms. I had to come up with different strategies to make it work (since Sun only provides very simple and basic examples). So I moved to raidctl to get rid of one of the complication factors (i.e. SVM). Costly options are not an option now under the current financial circumstances. FLAR is also an option if it would allow me to make a full backup of the disk. I found a lot of material about FLAR, but can you point me to something that talks about full disk image?
choogendyk, I am also using T5220 (and T2000). Can you share your script so I do not have to re-invent the wheel?
With regards to our business model, we install our application on Sun servers and sell them to our clients (OEM the HW); so we are responsible for the support. Since we partition the disks according to the application needs and manage mirroring, we have to come up with the backup strategy as well. In your case, you bring root partition down to make the backup, right? If that is the case, this means service outage in my case.

I want to increase the size of /tmp by 1GB
I know that the command is
chfs -a size=+1G /tmp
But the rootvg is mirrored and when I do a lsvg -p rootvg, I could see 2 disks.
Will there be any impact if I increase the size of /tmp when the rootvg is mirrored ?
Please advise. (1 Reply)

dgcfgbackup
dgcfgbackup(1M) dgcfgbackup(1M) 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
