Solaris10 -> iscsi -> equiliogic lun
We "lose" the iscsi device after a reboot - i.e., it appears in /dev/rdsk and /dev/dsk but format cannot find it. Obviously, it won't mount either. This happens for two separately defined luns.
We must be missing a step in iscsiadm.
The luns are defined as targets, we can see them in iscsiadm. We are not exporting them, so there is no backing store.

Hi,
I have an iSCSI LUN of 200GB. I increased it to 250GB and when I try to increase the size of the vg, I'm getting an error that none of the volumes have increased in size.
How can I get the OS to see the additional 50GB?

OCF_HEARTBEAT_ISCSI(7) OCF resource agents OCF_HEARTBEAT_ISCSI(7)
NAME
ocf_heartbeat_iscsi - Manages a local iSCSI initiator and its connections to iSCSI targets
SYNOPSIS
iscsi [start | stop | status | monitor | validate-all | methods | meta-data]
DESCRIPTION
OCF Resource Agent for iSCSI. Add (start) or remove (stop) iSCSI targets.
SUPPORTED PARAMETERS
portal
The iSCSI portal address in the form: {ip_address|hostname}[":"port] (required, string, no default)

Target discovery type. Check the open-iscsi documentation for supported discovery types. (optional, string, default sendtargets)
iscsiadm

udev
If the next resource depends on the udev creating a device then we wait until it is finished. On a normally loaded host this should be
done quickly, but you may be unlucky. If you are not using udev set this to "no", otherwise we will spin in a loop until a timeout
occurs. (optional, string, default yes)

start
Starts the resource. Suggested minimum timeout: 120.
stop
Stops the resource. Suggested minimum timeout: 120.
status

monitor
Performs a detailed status check. Suggested minimum timeout: 30. Suggested interval: 120.
validate-all
Performs a validation of the resource configuration. Suggested minimum timeout: 5.
methods

meta-data
Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5.
