TSM backup failure by NDMP 。error messages is ANR8844E Unable to open remote drive

[ Edited ]

Hello I connected TS3200 library to IBM N=series storage by FC .I used TSM server backup volume through NDMP .It works fine .

Yesterday ,I fond all backup job is failed . I check the actlog , Begin ,I guess the hardware is failed,so I change cable ,reboot the tape library ,delete drive ,redefine drive . but the problem is not resolved.

I checked tape library status in NAS storage ,connection is ok .But the tape drive format is wrong .

My NAS library status before mount tape

[root@TSM ~]# ssh nas1b mt -f rst1a status

Tape drive: IBM LTO-6 ULT3580

Status: offline

Format: LTO-4/5 Native Density

fileno = -1 blockno = -1 resid = 0

 

after some time ,a tape is mounted

[root@TSM~]# ssh nas1b mt -f rst1a status

Tape drive: IBM LTO-6 ULT3580

Status: offline

Format: LTO-6 6.25TB Compressed

fileno = -1 blockno = -1 resid = 0

 

TSM ACTlog :
