ioctl error

Chris C. Guevarra — Wed, 13 Apr 2005 22:02:18 GMT

Hi guys,

While performing Database ( SYBASE ) dump to tape, I receive the following errors.

Apr 12 08:00:00 2005: D00: SYBMULTBUF WARNING: Unable to initialize Async IO on the database device '/dev/vg29/rpns_d1'. Operating System call open failed with error code = 16 , Message= Device busy, State= 61.

Can somebody tell me the meaning of the error code " error code = 16 "

Hi Chris,

Have a look at here.

Hope this would be helpful.

Many databses require asyncrhonous I/O to work right. There is a setup file called /etc/setprivgrp that lets you allow for asyncrhonous i/o.

Other possible causes are writes that are not complete.

Thanks SEP

I think AIO is already set

[/]#getprivgrp
global privileges: CHOWN
