Virtual machines

and eligible lists
cp indicate queues exp
TCPIP
BKW
RSCS
TKNAIRB
REFSNID
FARMAN
EDLLNX2
VTAM
SSLSERV
VMLINUX1
VMLINUX
EDLLNX1
CORAK2
Notes:
1. Virtual machines are listed in priority order.
2. When INDICATE QUEUES EXP consistently shows E1, E2, or E3 (eligible) users, an eligible
list is forming because one or more system resources appears to be constrained.
3. The third column explains why a virtual machine is in a wait state:
v Rnn — current RUNUSER on the specified real CPU, where nn is the CPU ID (in
v IO — waiting for I/O
v PS — PSW wait (enabled wait state)
v PG — waiting for paging
I/O
cp indicate i/o (several times to see a pattern)
Example:
cp indicate i/o
FCONX
RTMTEST 73DF TOMDEF
Notes:
1. INDICATE I/O shows virtual machines currently in an I/O wait state and also shows the real
device number to which the most recent I/O operation was mapped. Four dashes (----)
indicates a virtual device.
2. If you see the same real device number for several virtual machines, this might be an
indication that there are many minidisks on the same DASD or you have a DASD controller
bottleneck, where too many DASD doing I/O are on the same controller.
