IBM LTO - IBM LTO5/6 Drives Not Working in Solaris 11 (Doc ID 1507743.1)

Last updated on MAY 22, 2017

Applies to:

IBM LTO5 Tape Drive - Version Not Applicable to Not Applicable [Release N/A]
Oracle Solaris on x86-64 (64-bit)
Oracle Solaris on SPARC (64-bit)

Symptoms

IBM LTO5, IBM LTO6 FC drives attached to S11 host.
Solaris detects the drive correctly & /dev/rmt/* links are built.
Netbackup can detect the drives with "scan" & "sgscan" commands and "robtest" is able to move medias.

Problem is observed while accessing the drives from NetBackup and with native Solaris commands like "mt" "dd" & "tar"

---- Errors ----
# dd if=/dev/rmt/0cbn bs=32k
dd: /dev/rmt/0cbn: open: I/O error

#mt -f /dev/rmt/Xcbn status
no tape loaded or drive offline

Same Drives work as expected from Linux.

Changes

 New Installation of drives in S11.
