Setting up tiered storage using ISP volumes
The following procedure illustrates how to establish a storage tier using ISP
volumes in a volume set.
To establish a storage tier using ISP volumes in a volume set
1
Use the vxdiskadm command or the GUI to create the disk group that will be
used to hold the tiered volumes and the volume set to which they will be
added. Add all the disks that are required to this disk group.
2
Define the rules to categorize the disks into storage tiers. This can be done
by disk vendor, array model, or by using the vxdisk settag command to
apply appropriate tags to the disks. The following example assigns cost tags
to disks from three different arrays:
# vxdisk -g dstdg settag cost=gold emc1_1 emc1_2
# vxdisk -g dstdg settag cost=silver hds1_1 hds1_2
# vxdisk -g dstdg settag cost=bronze jbod1_1 jbod1_2 jbod1_3
3
Use the vxpool command to create a storage pool in the disk group, for
example:
# vxpool -g dstdg create dstpool autogrow=diskgroup \
selfsufficient=pool
