Rebuild Rate : 20.00 %

[DPVamsi]

Hi,
In #sasmgr out put. The "Rebuild Rate" for root disk shows 0% and for secondary it shows 20%. What does that mean.

Is it that the Rebuild Rate is always 0% for Root disk.

the Out put below,

# sasmgr get_info -D /dev/sasd0 -q raid

The default value for rebuild rate is 20%.

You can change this to other values.

Hoo okay. Thank you Torsten.

I got it. but could you let me know how to modify it? also will that make any difference?

It's a sasmgr command, see

man sasmgr

example:

# sasmgr [-h][-f] set_attr -D device_file -q raid -q raid_vol=rvol_id -q
rebuild_rate=rebuild_rate

It's the rebuild priority.
