IML

Question

'The RE Directors had to be IML'd to get the A and B ports active' Could some one explain the IML here?

MrTS2Symm · Accepted Answer

The IML of a Director reloads the microcode for that Director and clears the registers of that same Director. I would guess (I'll say SWAG) that there was an issue that something was not logging in somewhere and needed to be cleared and let the initial handshake take place for communications.

There are 2 different types of IML's, one called a quick IML or a FD of the director. This is done when there are changes in the devices on directors or moves made that you want all directors to know about. Say a Control Center add or SDDR move. The other is a full IML, which was more than likely yours, and that is called a FE of the Director.

These are the terminologies that are used when EMC talks about IMLing a Director or why it needs to be done.

Initial machine load ...mini reboot if you will

MrTS2Symm · Answer

When a full or FE IML is done, more than likely manually, this is done in accordance to your approval and impact. What I mean by that, if EMC needs to IML Director(s), they would work with you to schedule that and more than likely be in the phone with you as this is going on. Or on the phone with the on site EMC representative that is contact with the Support Centre.

Hope that helps,

BTW, what do FD/FE stand for? There are two different type of IML's that a Symmetrix director can go thru. The first type is FD which is also know as a fast IML and an FE which is know as a full IML.
