rp5430 Health check


How do i do a health check on a rp5430. To check if any disks have io errors. If there is a faulty dimm or if a fan has failed and any other problem that there might be on the machine.

Thanks in advance

Re: rp5430 Health check

good morning!!

If you take a look at the output of cstm, that should give you all the information you're looking for. Run as follows:

# cstm
cstm>sall (for select all)
cstm>il (for information log)

when it starts scrolling, type 'q' for quit, then 'sa' for save as. Give it path and filename, (ie, /tmp/cstm.out)

Exit out of cstm, and view that output file.

Hope that helps.

Re: rp5430 Health check


first check whether disk is claimed or not using
#iosacn -fnC disk
u can use below commands for truobleshooting the disk problem
#diskinfo /dev/rdsk/c0t0d0
it should not show zero size. if it showing zero size means disk is faulty
dd to check that there are no I/O errors for the disks
#dd if=/dev/rdsk/c0t0d0 of=/dev/null bs=1024

Also u can compare the output of two commands
#strings /etc/lvmtab
#ioscan -fnC disk
for missing disk
some times disks(lun) will not be visible to server that time there may be the problem in FC card
u can check it using
#ioscan -fnC fc

For success, attitude is equally as important as ability

Hiya Sakhile!!

You could just 'choose' disk when looking at cstm. Check the man pages for that.

If you open up stm, it will give you a more graphical representation.
