Dear All,
I seek your views on following scenario.
I have 1 TS3500 Storage library with 12 drives of LTO4 then we expanded Library with LTO5 12drives.
Newly added 12 LTO5 drives are used for the backup of servers to one storage pool and backup size is more than 30 TB.
most of the clients uses LTO4 drives. All media used is LTO4.
While reviewing TSM server I have seen device class definition contains format=drive which is configured when I was not with organization. Now my client asking for go for LTO5 tapes. while reviewing TSM blogs I came to know the following.
1> format=drive is not recommended when you have mixed drive. Do I have to specify new devclass for LTO5 tapes?
2> you cannot keep mixed media in 1 storage pool not recommended.
3> I have tested that LTO5 tapes can be defined and mounted on LTO5 drive with the device class defined for the LTO4 storage pools it is because format=drive is mentioned in device class definition.
4> what Steps I have to do in order to use mixed drives and media in TSM properly.
5> Any issue I will get in case of any restoration?
Help will be appreciated.
Thanks
Abhijeet
