Tag names and tag values are case-sensitive character strings of up to 256 characters. Tag names can consist of letters (A through Z and a through z), numbers (0 through 9), dashes (-), underscores (_) or periods (.) from the ASCII character set. A tag name must start with either a letter or an underscore. Tag values can consist of any character from the ASCII character set with a decimal value from 32 through 127. If a tag value includes any spaces, use the vxassist settag command to set the tag on the newly created volume.
The tag names site, udid and vdid are reserved and should not be used. To avoid possible clashes with future product features, it is recommended that tag names do not start with any of the following strings: asl, be, isp, nbu, sf, symc, vx, or vxvm.attr.
You can use the tier attribute with the vxassist make command to set the vxfs.placement_class. tag on the volume being created. This attribute lets you set the volume tier that SmartTier will use. The following command adds tier1 to the vxfs.placement_class tag.
# vxassist -g dg3 make vol4 5g tier=tier2
# vxassist -g dg3 listtag TY NAME DISKGROUP TAG ========================================================= v vol4 dg3 vxfs.placement_class.tier2
