scsimgr or sasmgr

[Lukyflight]

To replace a SAS disk on an rx600, running 11.31, which command i have to use scsimgr or sasmgr?

Bonjour,

I guess that yes you still can use sasmgr with HP-UX 11.31.

man sasmgr, for "sasmgr replace_tgt -D device_file -q old_dev=lun_dsf -q new_tgt_hwpath=new_hw_path" says :

"The lun_dsf must be the legacy device file and the new_hw_path must be the legacy hardware path. This command does not allow a persistent device file or the new style hardware path to be specified with the old_dev and new_tgt_hwpath qualifiers."

Also from same manpage, you can use "io_redirect_dsf"

I must apologize :-(

Reading documentation at http://docs.hp.com/en/J6369-90071/J6369-90071.pdf, page 65 and later, I guess that sasmgr will only do the work on legacy dsf. If you use persistent dsf, you should also consider using "io_redirect_dsf"

also:http://www13.itrc.hp.com/service/cki/docDisplay.do?docLocale=en&docId=emr_na-c01037901-4 :
io_redirect_dsf is a new command introduced with HP-UX 11.31. It redirects the
persistent DSF from one device to a different device. This is equivalent of the command sasmgr replace_tgt.

It depends!

For hardware raids managed by the default built-in controller you just swap the disk and check with sasmgr.

For "plain" disks see

http://docs.hp.com/en/5992-3385/ch04s08.html#v1446838

For example:rx3600 a internal boot Disk, mirrord with UNIX. No raid over SAS Controller configured. Ioscan tell me Disk it's NO HW. I replace the disk. Ioscan show me the new disk. Then? sasmgr repace_tgt -D....? or scsimgr replace_wwid -D ..... and io_redirect_dsf -d .....?
Whit which operation i have to rplace the disk? scsimgr or sasmgr?

Did you follow the link above?

The link above does not work now in 2021. 

Still need to know how to format scsimgr replace_wwid disk I am getting an error.  0x1000002 is the new ID I pulled out of syslog. 

scsimgr replace_wwid disk 0x1000002 -D /dev/rdisk/disk12
scsimgr: ERROR: Invalid Keyword 'disk'
To view usage, run: scsimgr -h replace_wwid
