Are you using any SAN storage ..?

if please check your zone set configuration

if you think you've got some kind of HW issue going on and that you should check you HW logs for errors. Critical EMS entries will be in syslog.log or OLDsyslog.log.

yes, we are using SAN storage...

not only for disk... it is also not working for ext_bus,tape....etc

newapp:root-/>ioscan

newapp:root-/>ioscan -fnC ext_bus

newapp:root-/>ps -ef | grep -i ioscan
root 5088 4068 0 20:37:19 pts/0 0:00 grep -i ioscan
root 4988 4416 0 20:34:33 pts/2 0:00 ioscan
root 5084 4180 0 20:36:33 pts/1 0:00 ioscan -fnC ext_bus
newapp:root-/>

So, my point of view it is not an issue with storage...

Hi,

I got the output while issuing the following command,

newapp:root-/>ioscan -kfnC disk

ioscan -fnC disk is also now giving the output but it is taking apprx 4mins to give output..


So, what i should do???

dmesg --> do see any SCSSI reset something like that
/var/adm/syslog/syslog.log --> check look for any EMS --alert

insf -e --> Install device driver files
ioscan -fnC disk

bdf --> any file system full

are you using any external - storage disk ..?

Thanks,
Johnson
