Hi, I'm using AIX 5.2 and have a veritas volume of 2.1TB. When I use the IOCINFO ioctl call to retrieve the device info, I expect the flags in devinfo to be set with DF_LGDSK flag. But this bit is not set in flags. Is this a known issue with this ioctl ?? Because of this problem, I'm not able to get the proper disksize for devices > 2TB in my application. Alternatively, is there any other solution to find out the disksize. thanks, Randhir --------------------------------- Yahoo! India Answers: Share what you know.
