SAN Tape Backup and Ignite make_net_recovery

[Schneider H.-P.]

Hello,
im using Ignite C.7.2.94 and Tape Drives in a SAN. When I run a make_net_recovery on a 11.31 box while Backups on a 11.23 box are active the Tape Drives rewinds and the Tape Headers are overwritten. I have set "st_san_safe=1" but it seems it does not help on 11.31.
Does anyone have an idea?
greetings H.-P.

Hello,
i have other HP-UX boxes (11.11, 11.23) in the SAN, and the setting of "st_san_safe=1" helps. But not on 11.31

how about the parameter 'st_ats_enabled'? it must be set to OFF('0').

I found this in an other thread:

On previous versions of HP-UX the client had to issue the following
command:
# kctune st_san_safe=1

With HP-UX B.11.31, the command needed to get the same functionality is:
# scsimgr set_attr -d estape -a norewind_close_disabled=1

To preserve the change across reboots, the user must also run:
# scsimgr save_attr -d estape -a norewind_close_disabled=1

To confirm your desired settings, run:
# scsimgr -d estape get_attr

DRIVER estape GLOBAL ATTRIBUTES:

name = version
current = 0.1
default =
saved =

name = norewind_close_disabled
current = 1 <--- Here is the set_attr change
default = 0
saved = 1 <--- The save_attr will save the setting across reboots

name = st_ats_enable
current = 0
default = 0
saved =

For more information, read the scsimgr(1M) and scsimgr_estape(7) man
pages
or refer to the I/O subsystem section of the release notes for HP-UX 11iv3

I will test this
