4.7.2 Hardware Change Example for Virtual Volumes Created from CPGs
In the following example, the virtual volume
vv1
was created with the
createvv
command
while one cage of a two cage system was offline. Virtual volume
vv1
draws space from CPG
c1.
The Policy Advisor script analyzes the system and displays analysis and suggested actions
for improving performance.
The following example analyzes all virtual volumes in the InServ Storage Server that draw
space from CPG
c1.
On Linux or Solaris:
./PolicyAdvisor.tcl -cpg c1
On Windows:
policyadvisor -cpg c1
