You'll need to do that from a z/VM userid that has the proper CP privileges to
execute the ATTACH command (class B). You can determine if the guest has that
via a "vmcp q privclass" command:
s390vsw005:~ # vmcp q privclass
Error: Could not open device /dev/vmcp: No such device
s390vsw005:~ # modprobe vmcp
s390vsw005:~ # vmcp q privclass
Privilege classes for user LINUX005
Currently: BG
Directory: BG
My particular guest has both class G and B. Yours most likely will only have
G, in which case you'll need to get the z/VM systems programmer involved. If
it does have B, then:
vmcp attach 1008 \* 1008
Or, if virtual device number is already in use for that guest:
vmcp attach 1008 \* someothernumber
You'll then need to bring the FCP adapter online and configure it and the LUN
to access it.
