CommandviewSDM

Miles Denison — Sun, 02 Jan 2011 20:42:51 GMT

A bit of background first. I have a va7410, and a ds2405. After a long while of strenuous use my va7410 up and died, so I would like to throw the disks in the 2405. This would mean reformatting the block size from 520, to 512.

After installing commandview in order to issue a JBODfmt, I'm getting errors when trying to use it: "launcher" yields "Error getting database reference from localhost", and "armdiscover" comes back with "Failed to obtain remote database interface to host: localhost"

I have gone into the commIpAddr.txt, and access.dat and changed the IPs to match my current configuration (192.168.0.110). I've also uninstalled/reinstalled commandview a few times now to no avail.

I can view the disks with an ioscan just fine.

Is there some small step that I've missed during the install?

Thanks for any help,
Miles.

Please check this too:

/opt/sanmgr/hostagent/config/access.dat

as I mentioned above, I've checked access.dat and commIpAddr.txt already, and changed them both to 192.168.0.110.

If you are planning to use the disks in DS2405 without the VA7410, then there is no need to use armdiscover / launcher. These commands will work only when you have access to Lun0 on VA7410 on the host. If VA7410 is dead, you can not use these commands.

You can connect the DS2405 directly to the host and use them as normal disks and configure using LVM.

Ah. Well that would explain it.

In that case how would I go about reformatting those disks back to 512 block size? mediainit only works with a 512 size I believe.

I belive, it formatting to 512k block size will be automatically taken care via the usual process of adding the disks to LVM. I personally does not have any setup like this to test now.

No.

You need command view SDM to do this.

Remove the product, remove the files and directories that are left in /opt/sanmgr/ and install again:

rm -fR /opt/sanmgr

rm -fR /etc/opt/sanmgr

rm -fR /var/opt/sanmgr

Done, but again no change.

During the install procedure, when I am told to make sure that the correct services/daemons/scripts (technical term?) are running with ps "-ef |grep pfs" it only shows 4 of the 5 processes are running, "root 2592 2579 2 15:31:30 pts/tb 0:00 grep pfs" is not listed.

Could this have anything to do with the problem? I'm fairly new to the os.

Normally the problem is always the wrong IP in the config files, but if you delete them, it cannot be the problem any longer.

Do you still get the same error message?

There is also a "wrong" kernel parameter possible, but the system will tell you during the installation (max_thread_proc I think).

I've doubled the thread size from it's default. I've deleted the config files (access and commIpAddr), and when reinstalled played with the default configuration, wildcard, and a localhost address.

No luck yet.

Thanks for the help.

I've successfully done this in the past. Did you make sure that the drives are visible on the server? I beleive that Commandview SDM connects directly to the individual drives in a JBOD config.

If you are pretty sure the problem is Commandview SDM, you might try sg3utils, if you can build it on your system (or find binaries). I beleive there is a format utility in there that will also get the job done.

No idea why it still not works, do you have another server by chance? Maybe a windows host? Commandview is available for windows too.

Re: CommandviewSDM

I can successfully see every disk when I issue an ioscan, yes.

I'll check out sg3utils - and If needbe I can purchase a win 2k3 supported hba and toss it in one of my dl380s (maybe my next step).

Just out of curiosity, if indeed I preform a fimware reflash, would that then make the disk appear as a 512 sector size instead of the (rather unnecessary in my opinon) 520? and at that point could I use the pvcreate and lvm successfully? Just a thought I had.

Thanks for the help,
Miles.
