Basic Commands-hacv (CX3 series, CX series storage systems, and dual-SP AX4-5series running Navisphere Manager only)Checks whether the HA cache vault is enabled or disabled. HAcache vault determines the availability of storage-system writecaching when a single drive in the cache vault fails. When the HAcache vault is enabled, write caching is disabled if a single vaultdisk fails. When disabled, write caching is not disabled if a singledisk fails.-highReturns the write cache high watermark. The high watermark isthe percentage of dirty pages, which, when reached, causes the SPto begin flushing the cache.-lowReturns the write cache low watermark. The low watermark isthe percentage of cache dirty pages that determines when cacheflushing stops. When the write cache low watermark is reachedduring a flush operation, the SP stops flushing the cache.-mirrorReturns the write cache mirrored status. Always enabled for fibre.-pageReturns the size, in KB, of a cache page. This size can be 2, 4, 8, or16 KB. The default size is 2 KB.-pdpReturns the percentage of dirty pages currently in cache, that is,pages that have been modified in the SP’s write cache, but thathave not yet been written to disk. A high percentage of dirtypages means the cache is handling many write requests.-ppoReturns the percentage of pages owned by the SP.-rm3aReturns the amount of memory, in MB, reserved for theoptimized RAID 3 data buffers on SP A.-rm3bReturns the amount of memory, in MB, reserved for theoptimized RAID 3 data buffers on SP B.152 EMC Navisphere Command Line Interface (CLI) Reference
