I would not wish this on anyone. This is in accordance with the current T10 standards for the persistent reservations command set. This configuration provides eight paths to hdisks. Storage Subsystem worldwide name: The values are as follows:

This is done through the Storage Manager Client. One zone contains an HBA port and controller port from controller A.

This configuration provides four paths to hdisks. The array should now be in an optimal state. If you read enough IBM rdc notes, this text will be familiar to you: Sometimes IBM will check this for you, but ultimately you as the customer are responsible. Controller B will start charging its new battery as soon as its inserted.

Controller slides right out. This configuration provides eight paths to hdisks. Your email address will not be published. All disks of a storage model must be managed by the same driver. This configuration provides two paths to hdisks.

Insert the Controller back into its slot. Initiators from other host systems are required to register before they can access the device. That out rdca the way, you should have the replacement battery on-site. If you specify the -c flag, the command changes the driver selection to an alternate supported driver for the storage model. The values are as follows: And upgrade if necessary.

  DRIVER: BCM5703

This policy prevents other initiators in the same host or on other hosts from accessing the device. The way this bug was described to me was — if you have Hitachi drives with older firmware than FQ8 — as soon as you reseat your controller — all of your Hitachi drives will show up as failed.

When removing the fiber cables, keep them identified so that you have some way of reseating them in the correct order later on. Upgrading the drive firmware to FQ8 will prevent this problem.

I usually wait a minute before bringing the Controller back online. Reattach the battery access panel. Specifically, it displays information about the frame subsystemincluding the frame’s assigned name and worldwide name, and a es4300 of hdisks only those currently in the Available state associated with that subsystem, including the hdisk name, LUN number, current ownership, preferred path, and the user-assigned label for that volume.

Reconnect the fiber and network exactly as it was before. This policy uses the SCSI2 reserve to lock the device to a single initiator pathand commands routed through any other path result in a reservation conflict.
