We can find the drive serials and association through the StoreOnce CLI.
First we need to confirm if all drives belong to the same partition. This can be done by running "vtl show drive list":
# vtl show drive list
Object Type Library Name Status
------ ---- ------- ---- ------
DRV1 LTO6 LIB1 NAME_VTL01 Online
DRV2 LTO6 LIB1 NAME_VTL01 Online
DRV3 LTO6 LIB1 NAME_VTL01 Online
From the example above we know all drives belong to the LIB1 VTL and drives are called DRV<#>. With this information we can run the following command to get the details from the drive "vtl show drive info <set#> <library_name> <drive_name>":
# vtl show drive info set1 LIB1 DRV1
Drive Object : DRV1
Library : LIB1
Library Name : NAME_VTL01
Status : Online
Emulation Type : LTO6
Protocol : Fibre Channel
Serial Number : 1111150L01
WWNN : 50...F2
PORT : 1
FC Address : 0xB...1
WWPN : 50...F3
From the example above we can see the drive called "DRV1", from the library "NAME_VTL01" has the serial number "1111150L01".
Most if VTLs (if not all), name their drives after the bay so for DRV1 we can say the following:
Bay: 1
Drive: 1
Serial: 1111150L01
With this information we'll be able to add the respective drive on Bay1 and the same process would need to be done for the remaining drives.
Usually there's a sequence for the VTL serial numbers and finding the sequence is just as good.
Depending on the number of drives and other variables, the sequence could be numeric. eg: 1111150L01, 1111150L02, etc
It could also be alphabetical. eg: 1111150L0A, 1111150LB, etc.
Or even a combination from both. eg: 1111149L0Y, 1111149LZ, 1111150L01, 1111150L02, etc
