scsimgr set_attr not setting the attribute for estape

[George Barbitsas]

Hi,

I need to change the attribute norewind_close_disabled on a HP-UX 11.31 box. However, even though scsimgr says it's changed, the attribute stays at the same value, 0 :

[root@hpux01:~]scsimgr -d estape set_attr -a norewind_close_disabled=1
Value of attribute norewind_close_disabled set successfully
[root@hpux01:~]scsimgr -d estape get_attr -a norewind_close_disabled

DRIVER estape GLOBAL ATTRIBUTES:

name = norewind_close_disabled
current = 0
default = 0
saved = 1

This works fine on an other machine. I ran a tusc against scsimgr and it seems to be doing fine, I think this is the relevant portion, the actual operation :

open("/dev/escsi", O_RDWR, 0166070) ................................................................ = 8
ioctl(8, 0xdbb05371, 0x7fffd080) ................................................................... = 0

Any insight would be appreciated.

Just try this if it works for you:

# scsimgr -d estape save_attr -a norewind_close_disabled=1

Hi George, I tried it here (11.31.0809) and I'm able to set the parameter. Depending on what release you have, you should consider checking out PHKL_36312 but it has some warnings.

Thanks for the reply Olivier!

That patch isn't installed, but it's not installed on our other itanium machine either and the parameter is correctly set there. We already had a reboot planned for some other work this weekend and the saved parameter is correct, so we'll see if that solves it first, then i'll look into the patch you sent with the backup people (for the compression issue) and install if everything is ok.
