Hi All,
This might be a stupid question, but I got some complaints about intermittent
long queue length
on our disks. We already have the load spread out, raid, etc. My question
is focused on the hsz's. I noticed our disk units on the hsz's has
nowriteback_cache
set and I plan to turn that on. Management wants to discuss this before I
enable it so
I need to double check something. We have dual redundant hsz 70's. If I do a
"show this"
on one hsz, it shows no unflushed data in cache. If I do a "show other",
it shows there is
unflushed data in cache.
Is this a problem or is this normal behavior and I'm just catching it in the
inbetween states of the show commands?
Since the disk units has nowriteback_cache set, I'm not sure
where the data in cache is from in the first place.
I don't see any cache policy, but I do see Host Functionality Mode = A.
Cache_flush_timer is set to the default, 10 seconds.
nocache_ups.
32 megabyte write cache, version 4
cache is good
battery is good
Pretty much the same info with Mirrored Cache.
thanks for any info.
Allan
