Data Backup and Recovery
Hi folk,
I'm trying to run SDU on RedHat 5.3 with FC. Hba is an Emulex. I'm using HU 4.1.2 and SDU 4.1.1. The problem occurs when SDU is trying to discover the LUN (I guess SDU has a problem with SCSI rescan process).
[root@lx-smo-fcp ~]# snapdrive storage create -lun nacl2:/vol/toto/lun3 -lunsize 200m -fs /toto
LUN nacl2:/vol/toto/lun3 ... created
mapping new lun(s) ... done
discovering new lun(s) ... *failed*
Cleaning up ...
- LUN nacl2:/vol/toto/lun3 ... Cleanup has failed.
Please delete LUN
nacl2:/vol/toto/lun3
0001-267 Command error: Could not find SCSI devices
You can find an extract of sd-trace.log :
9:00:41 09/29/09 [7813b90]?,2,2,0001-267 Command error: Could not find SCSI devices
19:00:41 09/29/09 [7813b90]?,2,2,0001-267 Command error: Could not find SCSI devices
19:00:41 09/29/09 [7813b90]?,2,2,0001-984 Admin error: Failed to get the physical devices associated with nacl2:/vol/toto/lun3 (6)
After cleanup, whether I remap the LUN, the LUN access is OK and sanlun displays the right thing and the multipath is working.
Any idea ? (You will able to find the SDU log file in attach)
Regards,
Mathias
Solved! See The Solution
I've observed similar behavior when sg_utils was not installed? Have you installed?

How do you install SG3 utils on RHEL4 w/o yum? It's telling me command not found. I'm not too proficient with linux.
What are SG3 utils? What does it do?
I'm receiving the same error and think this may be my problem.
Have a look at the following for the sg3_utils install.

Thanks. I am trying to install and it needs a dependency. see below
[root@BastestLinux ~]# rpm -U -v /tmp/Redhat/sg3_utils-1.22-3.1.x86_64.rpm
warning: /tmp/Redhat/sg3_utils-1.22-3.1.x86_64.rpm: V3 DSA signature: NOKEY, key ID db42a60e
error: Failed dependencies:

Suggested resolutions:
/var/spool/up2datesg3_utils-libs-1.22-3.1.x86_64.rpm
Where can I get that I searched the redhat site and could not find this lib
I found the lib and got sg3 utils installed. thanks
I have a similar problem creating a LUN with snapdrive but the sg_utils are installed (RedHat 6.0)
Thanks in advance for your help:

How are you?
Please check

Hi neto,
Thanks a lot for your help.
iSCSI will be used, so the command shows nothing:
[root@nb2cm004 ~]# sanlun fcp show adapter -v
Unable to locate /usr/lib/libHBAAPI.so library
Make sure the package installing the library is installed & loaded
Sometimes the "snapdrive storage show -all" results in an error message:
[root@nb2cm004 ~]# snapdrive storage show -all
raw device: nb2cm005.ww003.siemens.net:/vobstore2 mount point: /net/nb2cm005.ww003.siemens.net/vobstore2 (non-persistent) fstype nfs
