    Unanswered: chunk errors

    Hi guys, looks like Im facing an issue with disks

    online.log is bellow.

    everything i read about CLNT_PAM_CAPABLE error points to a bug and i need to upgrade the engine, but what to do with
    13:48:06 I/O read chunk 18, pagenum 519153, pagecnt 1 --> errno = 5
    im not sure yet, HP is not reporting any errors according to /var/adm/syslog
    or gvdisplay and lvdisplay commands.


    the system is not mirrored, if these are disk errors what should i do?
    I was thinking about creating an additional dbspace, recreate the tables that live in chunk 18 there and rename the tables in chunk 18 to table_name_old or something so nothing new would get written there.
    Is there any way to find out which table lives on pagenum 519153?
    Any suggestions?

    get what tables on chunk 18 and what table is page 519153 ...
    oncheck -pe

    print the page with error...
    oncheck -pP 18 519153

    about coping the table to another dbspace, is not a bad idea... but you need discover if the problem is your disk devices or not...

    sorry my bad english...

    Thank you for your help on identifying the tables.

    I created the new dbspace and now copying tables out there.
    Looks like it's helping, time will tell.

    Cheers

    Artem
