Alternate System Volume Troubleshooting
Problem Recovery  (page 1 of 2)
DSM/SCM stops and 
issues an EMS message 
st
ating that a conflict exists 
between volume/alternate 
volume name pairs.
Volume and alternate volume name pairs must be unique. (For 
example, $DATA $SYSTEM and $SYSTEM $DATA are not 
allowed.) Because a volume might be active under either its 
volume name or its alternate volume name, it is not possible to 
uniquely determine a volume for placing software if two active 
volumes are up that have reversed volume/alternate volume 
names.
Use SCF to rename one of the volumes.
When you perform a target 
activity
, an
 EMS message 
states that no scratch 
volumes are configured on 
the target system.
Either you did not run the ZPHITMI on the target system after 
running INITENV, or you changed the primary or alternate 
name of a scratch volume. 
1. Run ZPHITMI.
2. Define at least one scratch volume using the Volume 
Maintenan
ce screen.
3.
Define at least one operator for running the ZPHITI using 
the Operator Security Maintenance screen
.
The host database cannot 
locate volumes af
ter their 
names were changed 
outside DSM/SCM.
Request an independent snapshot from the ZPHITI to update 
the host database with the new volume names.
The ZPHIHMI or ZPHITMI 
does not displa
y a certain 
disk volume on its Volume 
Maintenance screen. 
The disk volume might have a duplicate set of primary and 
alternate names. DSM/SCM ignores these volumes and does 
not display them.
For a volume pair that is 
not physically pres
ent in 
the system, DSM/SCM 
stops and issues a 
message stating that a 
TSV volume volume- 
name alternate-volume -
name is not online. 
You renamed or deleted a volume and another down volume 
exists, with the same name as the original primary or alternate 
name of the renamed or deleted disk.
For example, you renamed $A ($B) disk to $P ($Q). However, 
if a down volume alre
ady has the name $B, DSM/SCM issues 
the error message, “TSV volume $A $B not online.” 
Bring up the down volume or delete the down volume entry 
from the configu
ration, run Verify Database, and perform the 
Independent Snapshot activity.
