Not having GK and issuing symcli commands may be very dangerous. Symcli commands may use your devices and "lock" them to issue commands against the storage. This may impact your applications.
The below information is from ECC 6.0 help, ControlCenter will look for and use the smallest available device first as a Gatekeeper, but if none are available, it will use any device, regardless of size, as a Gatekeeper device
Gatekeeper Device Definition:
- Less than 10 Cylinders in size.
- May or may not have the Gatekeeper attribute set via SYMCLI symgate define command.
- Used to manage SYMAPI traffic between a host and a Symmetrix array.
Gatekeeper Devices in ControlCenter:
- ControlCenter via Solutions Enabler uses Gatekeeper devices to perform SYMAPI tasks.
- ControlCenter automatically identifies Symmetrix devices less than 10 cylinders in size
as Gatekeeper devices (Gatekeeper attribute set or not).
- ControlCenter will look for and use the smallest available device first as a Gatekeeper,
but if none are available, it will use any device, regardless of size, as a Gatekeeper device.- ControlCenter can create Symmetrix devices of varying sizes, including devices less than
10 cylinders in size.
- Verify that any devices created via ControlCenter are Masked to the host intended to use them.
Primus emc180055 gives a good description of what gatekeepers are and how many are needed. For a description on how gatekeepers are selected see emc25807.
I don't know what happened, but iview doesn't work for me anymore..... I will have to dig into this and get it fixed. So I can't view these primus cases anymore.
