Special Instructions

(CLARiiON only): Linux Navisphere Agent/CLI limitation with fdisk

on CLARiiON

There is a known issue with the Linux Naviagent/CLI in which the

Naviagent does not close the sd devices before becoming a daemon

and, as a result, the devices remain open. This may cause issues when

attempting to access devices.

For example, if the Naviagent service is left running and someone

runs

fdisk to create new partitions on CLARiiON storage devices,

any attempt to make a new filesystem with

mkfs on the newly created

partition(s) will fail.

An example of a warning issued when

fdisk is run is:

WARNING: Re-reading the partition table failed with

error 16. Device or resource busy. The kernel still

uses the old table. The new table will be used at next

reboot.

If, after receiving the above warning, the user attempts to run mkfs

on a newly created filesystem, mkfs will also fail with an error similar

to the following:

mke2fs.ext2: No such device or address while trying to

determine filesystem size

This problem may be resolved in on of the ways described in detail in

the following list:

◆ Disable the Naviagent/CLI service.

◆ Issue a Naviagent stop command:

• On RHEL, issue the command:

service naviagent stop

• On SLES , issue the command:

/etc/init.d/naviagent stop

◆ Remove the Naviagent/CLI RPM.

◆ Rescan the SCSI bus.
