scsimgr replace wwid
Hi
I have seen the following error in the syslog . I know this happened when the new disk which we added and removed later which had the device files
The OS is 11.31
Nov 18 10:24:14 prod1 vmunix: Evpd inquiry page 83h/80h failed or the current page 83h/80h data do not match the previous known page 83h/80h data on LUN id 0x0 probed beneath the target path (class = tgtpath, instance = 38) The lun path is (class = lunpath, instance 601).Run 'scsimgr replace_wwid' command to validate the change
its repeating with instance 602,603,604
I removed the device files with the following steps
root@prod1:/usr/local/bin : ioscan -fnC disk | grep -i no_hw
disk 704 2/0/12/1/0/4/0.1.18.0.0.1.6 sdisk NO_HW DEVICE IBM 2145
disk 702 2/0/12/1/0/4/0.1.50.0.0.1.6 sdisk NO_HW DEVICE IBM 2145
disk 703 3/0/12/1/0/4/0.2.2.0.0.1.6 sdisk NO_HW DEVICE IBM 2145
disk 700 3/0/12/1/0/4/0.2.34.0.0.1.6 sdisk NO_HW DEVICE IBM 2145
root@prod1:/usr/local/bin : lssf /dev/rdisk/disk701
esdisk section 0 at address 64000/0xfa00/0xc8 /dev/rdisk/disk701
root@prod1:/usr/local/bin :
root@prod1:/usr/local/bin : rmsf -H 64000/0xfa00/0xc8
root@prod1:/usr/local/bin : ioscan -fnC disk | grep -i no_hw
IS this enough to clear the error and correct , I have seen in some other servers some scsimgr command issued before removing the device files
Like this
scsimgr -f replace_wwid -C lunpath -I 600
What exactly this does , and what is the use of this command and what is happening in background

Re: scsimgr replace wwid
root@prod1:/ : scsimgr get_info -C lunpath -I 600
STATUS INFORMATION FOR LUN PATH : lunpath600
Generic Status Information
SCSI services internal state = UNOPEN
Open close state = AUTH_FAILED
Protocol = fibre_channel
EVPD page 0x83 description code = 1
root@prod1:/ : scsimgr get_info -C lunpath -I 603
STATUS INFORMATION FOR LUN PATH : lunpath603
Generic Status Information
SCSI services internal state = UNOPEN
Open close state = STANDBY
Protocol = fibre_channel
root@prod1:/ : scsimgr get_info -C lunpath -I 602
STATUS INFORMATION FOR LUN PATH : lunpath602
Generic Status Information
SCSI services internal state = UNOPEN
Open close state = ACTIVE
Protocol = fibre_channel
So I need to issue the replace_wwid command only for 600 instance right ?
root@prod1:/ : scsimgr -p get_attr -C lunpath -I 600 -a hw_path
3/0/10/1/0/4/0.0x5005076801205aaf.0x400e000000000000
root@prod1:/ : lssf 3/0/10/1/0/4/0
lssf: 3/0/10/1/0/4/0: No such file or directory
root@prod1:/ : lssf 3/0/10/1/0/4/0.0x5005076801205aaf.0x400e000000000000
lssf: 3/0/10/1/0/4/0.0x5005076801205aaf.0x400e000000000000: No such file or directory
root@prod1:/ :
To be issued
scsimgr -f replace_wwid -H 64000/0xfa00/0xc2 right ?
required for all other , or only this AUTH Failed
