Virtual TapeServer 6.04.03 Installation Guide

14 | Creating Virtual Tape Drives
11. In the Serial Number field, specify the serial number of the VTD. You can specify up to
10 alphanumeric characters. This string is presented to the host and should be unique
(across all VTS servers and VTDs in the environment). If you do not specify a serial
number, it is automatically generated.
12. Click Submit.
It is recommended that you back up the VTS database after modifying the VTS configuration.
Refer to the Virtual TapeServer Operations and Administration Guide for instructions.
Configuring the NonStop BladeSystem Cluster I/O Module
If the NonStop BladeSystem is used as the host server and the Cluster I/O Module (CLIM)
will be used, you must configure the virtual tape drives on the NonStop. Complete the
following steps to do so:
1. Verify that the serial number specified for each virtual tape drive (in VTS) is unique. See
step
11 on page 14 for more information.
2. Verify that the CLIM is connected to the VTS server using a Fibre Channel cable.
3. Issue the following command on BladeSystem server to verify the list of devices, including
those configured in VTS:
CLIMCMD clim_name lunmgr -f
Here is an example of the output:
dev type stable address controller serial # revision
sg0 3 tape CPQNSD 5257 #VFHP00 slot 1, port 1 VFHP00 VT36
sg1 3 tape CPQNSD 5257 #VFHP01 slot 1, port 1 VFHP01 VT36
sg2 3 tape CPQNSD 5257 #VFHP02 slot 1, port 1 VFHP02 VT36
sg3 3 tape CPQNSD 5257 #VFHP03 slot 1, port 1 VFHP03 VT36
sg5 3 tape CPQNSD 5257 #VFHP04 slot 1, port 1 VFHP04 VT36
4. If you do not see devices, issue the following command to scan the devices and detect new
devices:
CLIMCMD clim_name lunmgr -s
5. If the devices are not listed again, issue the following command, which enables you to set
LUNs:
CLIMCMD clim_name lunmgr -a, VERBOSE
6. If steps 4 and 5 are successful, issue the SCF command to add a tape. Here is an example:
SCF ADD TAPE $VFHP00, SENDTO STORAGE, CLIM S1002531, LUN 1,
PRIMARYCPU 2,BACKUPCPU 2.
7. Start the virtual tape drive. If a 224 error occurs, delete the drive and make sure steps 4
and 5 are successful.
