Only 1 path active on XS which is part of the pool

While creating new SR on XS 6.0.2 on EMC VNX 5500 will show one host with 1 active path rest all have all the active path . When multipath -ll is run it will also show one path . This shows that all the path is not having access to the lun .

From the host which has an issue logoff all the active path

iscsiadm -m node -U all  and then logback in iscsiadm -m node -L all.

Restart the multipathd service /etc/init.d/multipathd restart. This will bring all the path active on the host.

Using ISCSIADM on XenServer 6.0.2: Message "ISCSIADM is not running " could not start Automatically

Installed brand new XenServer and try to run ISCSIADM command it will throw message  "iscsid is not running. Could not start it up automatically using the startup command in /etc/iscsi/iscsid.start

image

To  fix it just run new SR wizard for ISCSI over LVM and

then try to run the discovery again it will list all the targets . This test is conducted on EMC VNX 5500. This process basically make  open-iscsi service is called by and configured by XAPI. When using the New Storage wizard, it will create files /etc/iscsi such as initiator name, send_targets directory. image

In order to create new SR on VNX 5500 for XenServer 6.0.2 , you need to ensure that all the targets are logged in. The process is A) Run SR wizard but do not create SR 2) Logged all the targets 3) Create the SR again using SR wizard   . This has been explained in following blogs of mine

Thanks to my college and open-iscsi.

Dell OpenManage Server Administrator (OMSA) installation on XenServer 6.0.2

In order to install OMSA 6.5 on XS 6.0.2 , we need to get latest ISO from Dell site. Connect this ISO to the Dell Server via virtual CD ROM

image

Mount the CD-ROM on XenServer and run the install.sh script to start OMSA agent on XS.

This will install the require package

Insure the ports are open. By default installation does open the require ports

Start the server service
