Apple Xsan 2 - Manual (Page 152)

152 Appendix C Use command-line tools
Label a LUN:
$ sudo cvlabel [-v] [-f] [labelfile]

Xsan Admin to label LUNs is safer, because it only shows available LUNs.
Remove the label from a LUN:
$ sudo cvlabel -u lun
Parameter Description
-l List available LUNs.
-s Display device serial numbers.
-v Show progress display.
-c Create a label template file.
-f Relabels LUNs that are labeled.
labelfile An optional file containing information for each
label. You can use the -c option to create this file.
lun The LUN identified by disk name—for example:
/dev/disk4.
-u Unlabel the specified LUN.
Create a folder and assign an affinity (cvmkdir)
Use the cvmkdir command to create a folder (directory) and assign it an affinity tag so
that its contents are stored on storage pools with the same affinity tag.
$ cvmkdir -k affinity folder
Parameter Description
-k affinity Specifies the affinity tag to be associated with the
folder.
affinity – the affinity tag that’s assigned to
the storage pools where you want the folder’s
contents to be stored
You can use the
show long command of the
cvadmin tool to see a storage pool’s affinity tag.
You can use -k "" to remove the folder’s
affinity tag.
folder The path to and name of the folder.
