Thank you.
I may not be in as bad of shape as I think i am. lslv -l hd2 shows hdisk1 with a 0% in the IN BAND column, which from the man pages sounds like the OS is not writing to the lv anymore.
returns with no errors.
It almost seems like i could just pull hdisk1 out and be ok at this point. Its a gut wrenching decision (probably wont do it though). I have re-ran bosboot -ad /dev/hdisk0 and made sure my bootlist lists hdisk0 first. If there was trouble as far as os problems, I would expect my OS by now to be choking and dying if I had any filesystem access, os command errors, accessing hdisk0, however, its still running fine (running DB2 and Informix developement DB's).
Hello,
how can i see easily the state of a mirrored disk on a AIX 4.3.3.
I try followed command:
lslv -m >lvname> but for me is not enough information.
thanx in advance

I've looked a little but haven't found a solid answer, assuming there is one.
What's better, hardware mirroring or ZFS mirroring? Common practice for us was to use the raid controllers on the Sun x86 servers. Now we've been using ZFS mirroring since U6. Any performance difference? Any other... (3 Replies)

usleep
USLEEP(3) BSD Library Functions Manual USLEEP(3)NAME
usleep -- suspend execution for interval of microseconds
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <unistd.h>
int
usleep(useconds_t microseconds);
DESCRIPTION
The usleep() function suspends execution of the calling process until either the number of microseconds specified by microseconds have
elapsed or a signal is delivered to the calling process and its action is to invoke a signal catching function or to terminate the process.
The suspension time may be longer than requested due to the scheduling of other activity by the system.
The microseconds argument must be less than 1,000,000. If the value of microseconds is 0, then the call has no effect.
RETURN VALUES
On successful completion, usleep() returns 0. Otherwise, it returns -1 and sets errno to indicate the error.
ERRORS
The usleep() function may fail if:
[EINVAL] The microseconds interval specified 1,000,000 or more microseconds.
SEE ALSO nanosleep(2), sleep(3)STANDARDS
The usleep() function conforms to X/Open Portability Guide Issue 4, Version 2 (``XPG4.2''). It later appeared in the POSIX standard, but in
IEEE Std 1003.1-2004 (``POSIX.1'') it was marked as legacy and the use of nanosleep(2) was recommended instead. The IEEE Std 1003.1-2008
(``POSIX.1'') revision removed usleep() from the specification.
HISTORY
The usleep() function appeared in 4.3BSD.
