NDMP of thin provisioned data generates TAPEALERTs
Thats the way it looks at least.
Newly implemented stunit on filer, I backup a thin lun and it gets upset in different ways:
Warning bptm (pid=12238) TapeAlert Code: 0x27, Type: Warning, Flag: DIAGNOSTICS REQ., from drive IBM.ULTRIUM-TD4
TapeAlert Code: 0x37, Type: Critical, Flag: LOADING FAILURE, from drive IBM.ULTRIUM-TD4...
Im sure its data related, these drives are otherwise fine. When the backup runs you see the job sit there and having done the data, it sits for some minutes dealing with the sparsity it seems...the KB/sec gradually decreases and at end of job it spits out a tapealert message.
The jobs complete wih code 0.
Drives are lto4, filer is netapp 8.x.y, under netbackup 7504 solaris master..
Firmware, or a tweak possibly?
Your input appreciated.
