Slow response of the server

[UniRock]

Hi All,

My server 11.23, rx8640 is responding slow when I run commands like ll, su etc.
Database running is Orcale.
What could be the issue?
Attaching the few o/p.

Thanks,

Hi

Use ioscan command to check that disk has claimed status or no_hw status

or do

strings /etc/lvmtab |grep c0t0d0

check which vg is using that disk
after that do lvdisplay -v |more

check any stale extents are there or not???

Hi Sunny,

Disks are CLAIMED and both of them are used in VG00....They do not have stale extents.

Thanks..
