Ora-27603:ora-27626:

Hi,

User claim that job is running slow from their end.
I DBA found in database the below errors in alert log file.

ORA-27603: Cell storage I/O error, I/O failed on disk o/192.168.10.3/RECO_DM01_CD_01_drm01 at offset 13335789568 for data length 1048576
ORA-27626: Exadata error: 2201 (IO cancelled due to slow/hung disk)

This error looks like some issue with server end.
Could someone please tell me the checks to perform in server as this server is managed by DBA team. So I cannot ask Unix team to look into it.

OS -- Linux

Maddy

Hi Maddy,

You could start by having a look in "/var/log/messages" for any errors, if the logging is setup then you should see something there which may be of more help.

I'd also at this point be tempted to ensure that there are valid backups for the server, I'd guess at a head crash on the hard drive.

Hi,
What does the following command on the storage server reveal?

cellcli -e list alerthistory
