Reverting to Default-VPU Assignment
Before you enable the direct volume, you can remove the manual-VPU assignment.
This causes the namespace software to assign the volume according to the default
rules (refer back to “Default-VPU Assignment” on page 8-20). From gbl-ns-vol
mode, use the
no vpu command to revert to default-VPU assignment:
no vpu
For example:
bstnA6k(gbl)# namespace medarcv
bstnA6k(gbl-ns[medarcv])# volume /test_results
bstnA6k(gbl-ns-vol[medarcv~/test_results])# no vpu
bstnA6k(gbl-ns-vol[medarcv~/test_results])# ...
VPU Limits for Direct Volumes and Shares
The number of VPUs on your platform determines the maximum volumes and shares
you can add. Table 8-2 specifies limits on volumes and direct-volume shares for each
platform.
