Tape Label : Solaris 9 Legato NW 7.2.2 : Label Block size Problem
I think that the default label block size of LTOII IBM with solaris is 64KB. I have label new tapes without problem. A storage node ( solaris) come and load the tape and say
"media warning: rd=xxxxx:/dev/rmt/5cbn opening permission denied
media notice: volume FJ0xxx on device rd=xxxxx:/dev/rmt/5cbn : Block size is 32768 bytes not 64536 bytes. Verify the device configuration. Tape positioning by record is disable"
the tape was newly on solaris new labled. The device block size on the gui is " "hanler default".
we try to with 64KB it came the same problem...
what's the problem or the solution?

That block size can be changed by special NSR environment variable.
No matter what you set for NW OS can still change it via setting in st.conf.
However I think your problem might not be block size related as first error message is permission denied on 5cbn. I would suggest to make few tests with tar or dd between server and storage node and see what happens.

And I do all of OS(use networker backup) the same block size,so the networker work with no problem.
I think you do this solution in SAN,so have this problem.

Block size :
in S95networker :
NSR_DEV_BLOCK_SIZE_LTO_ULTRIUM_2=64
export NSR_DEV_BLOCK_SIZE_LTO_ULTRIUM_2
This will correct the problem that the tapes are set full with low data :
In st.conf
"IBM ULTRIUM-TD2", "IBM Ultrium-2", "CLASS_LTO2",
CLASS_LTO2 = 2,0x3B,0,0x38619,4,0x40,0x40,0x42,0x42,3,60,1080,540,9060,720,660,9060;
Und aktivierung ohne reboot durch :
/etc/rc2.d/S95networker stop
modinfo |grep SCSI
modunload -i
modload /kernel/drv/st
drvconfig -i st
tapes
inquire
/etc/rc2.d/S95networker start
