bstnA6k(gbl-ns-vol[medco~/vol])# share sales
bstnA6k(gbl-ns-vol-shr[medco~/vol~sales])# no enable
bstnA6k(gbl-ns-vol-shr[medco~/vol~sales])# ...
Removing a Direct Share
Use the no share command to remove a share from a direct volume:
no share
For example, this command set removes the “test” share from the “/vol” volume in
the “medco” namespace:
bstnA6k(gbl)# namespace medco
bstnA6k(gbl-ns[medco])# volume /vol
bstnA6k(gbl-ns-vol[medco~/vol])# no share test
bstnA6k(gbl-ns-vol[medco~/vol])# ...
Selecting a VPU (optional)
The next step in configuring a volume is to choose its Virtual-Processing Unit (VPU).
A VPU is a virtual CPU that can fail over from one chassis to another in a redundant
configuration. The namespace software chooses a default VPU if you do not
explicitly choose one.
Each VPU runs on its own physical processor during normal operation; after a
redundancy failover, a single physical processor can run two VPUs. In the ARX®500
or ARX®1000, a single VPU runs on the ACM and can fail over to its redundant
peer’s ACM. In an ARX®6000, two VPUs run on each ASM (an ASM has two
processors, each of which supports one VPU).
The default-VPU assignment rules (described next) can artificially reduce the maximum
number of namespaces for the host switch. Once the volume is enabled, its VPU
assignment is permanent. Read this section carefully before using the default-VPU
assignment.
