On the UNIX system, by using the volume list creation and display function by means of the iSMvollist
command, it is possible to obtain and display special file name, logical disk name, and associated OS
type (hereafter, volume list) of the logical disks in the disk arrays.
To use the replication operation function, it is necessary to create the volume list beforehand by
executing the iSMvollist command because only the volumes that have already been registered in the
volume list are targets.
Only an appropriate privileged user (superuser) can create or update the volume list.
When you have added or deleted disk arrays to or from the system or built or cancelled logical disks,
you must update the volume list to reflect the information. If the volume list is not updated, data
inconsistency may occur during data replication and snapshot operations.
[Main Options]
The following options can be specified in the iSMvollist command.
(i)
Creating/updating the volume list (-r)
It is possible to scan devices connected to the system and create or update the volume list.
The volume list can be automatically created at the start of the business server. However, if
settings remain unchanged since installation, the volume list cannot be automatically created, and
therefore, will need to be manually created. To automatically create it, it is necessary to change
the name of the rc file that has been created at the installation.
The HP-UX system executes ioscan(1M) to obtain device information when the volume list is
created (iSMvollist -r). To do so, it uses the -k option so as to obtain device information from the
kernel rather than from the actual hardware. Therefore, even though the hardware is made
available, the actual hardware may not be made available. In this case, creation or update of the
volume list fails and the following message appears.
iSM11758:
System call error (error code=214)
If this error message appears, execute the ioscan -fn to confirm the state of the actual hardware.
(ii) Displaying the volume list
One of the following options can be selected.
-d option:
Lists disk array information.
-l option:
Displays information associated with all logical disks.
-vs option:
Displays information only associated with specified disk arrays sorted by
using special file name as the key. If a specific special file name is
specified, the system displays information only associated with the specified
