AFTD record size / block size / write size mismatch

[StevieOnsite]

Hi,

my EBS configuration here is completely based upon AFTD's.

For Tuning purposes we set generally:

NSR_DEV_BLOCK_SIZE_ADV_FILE=1024
export NSR_DEV_BLOCK_SIZE_ADV_FILE

EBS is confirming this setting in /nsr/logs/messages as:

root: [ID 702911 daemon.notice] Sun StorageTek(TM) Enterprise
Backup media: (notice) setting (adv_file) block size to (1024 KB)

But when I issue a simple scanner -vv on on of the
AFTD's I'm stuck with the displayed record size
of 131072 which is just 128kb.

Finally, when you monitor the write syscalls of nsrmmd's via truss the maximum value is 1048076, which is just
500 bytes less than 1024k.

Any hints concerning this mismatch, looks like a bug to me.

Regards

Stevie
