Creating Meta's in ECC
The first step in giving a host access to EMC disks is to actually create the metas themselves. The metas are logical collection of standars that are set up to look like a single device to the actual hosts. Always use/create RAID5 devices as concatenated, RAID1 devices as striped.
1. In ECC select:
- Storgare systems
- Symmetrix Arrays
- Right click on the appropiate Symm
- Select configure
- Select Meta Device Configuration
2. On the left side select the appropiate Unmapped Devices
- BCV Devices are for Business continuous volumes
- Standards are for regular volumes
- For RAID5 volumes select four contiguous standards/BCV (this is what we do, this isn't what everyone does)
3. On the right side select the correct type of Meta Device you wish to create. Always use/create RAID5 devices as concatenated metas , RAID1 devices as striped metas.
4. Push the Create Meta button!
Note: The newly created Meta Devices will be created using the first standard/BCV in the meta as it's identifier. This number, the meta head, is not the LUN Device name/number.
