|
| vxassist -g disk_group -U vol_type make volume_name
length layout=stripe disk_list |
| |
|
| Creating a striped-mirrored volume using vxassist
|
| vxassist -g disk_group -U vol_type make volume_name
length layout=mirror mirror=cntrl stripe_stripeunit=? disk_list |
| |
|
| Stopping and Starting a volume |
| vxvol -g disk_group start volume_name => to
start |
| vxvol -g disk_group stop volume_name => to
stop |
| |
|
| Listing unstartable volumes |
| vxprint -ht | grep DISABLED |
| |
|
| Removing a volume |
| vxedit -g disk_group -r rm volume_name |
| |
|
| Removing a volume recursively |
| vxedit -g disk_group -vrf rm volume_name |
| |
|
| Growing a file system or volume using vxresize
command |
| vxresize -F -ufs -g disk_group volume_name +space_to_add |
| |
|
| Creating and mounting a file system on a volume
|
| 1. Create a volume |
| 2. newfs on the newly created volume |
| newfs /dev/vx/rdsk/volume_device |
| 3. Create a mount point |
| mkdir /mount_point |
| 4. add the new file system entry in the /etc/vfstab
file |
| 5. now mount the file system |
| mount /file_system |
| |
|
| Removing a mirror |
| 1. dettache the plex from the volume |
| vxplex -g disk_group dis plex_name |
| vxedit -g disk_group -prf plex_name |
| |
| OR |
| vxplex -g disk_group rm dis plex_name |
| |
|
| Adding a DRL log to an existing volume |
| vxassist -g disk_group addlog volume_name disk |
| |
|
| Removing a DRL log |
| vxassist -g disk_group remove log volume_name
|
| |
|
| Adding a Raid-5 log |
| vxassist -g disk_group addlog volume_name disk |

|
| Changing group, owner and mode on a volume |
| vxedit -g disk_group set user=??? group=??? mode=???
