Basic Commands-prbReturns the percentage of the LUN that is rebuilt.-prefetchReturns the prefetch type that the LUN is using for read caching.The possible output follows.Variable length prefetching YESConstant length prefetching YESPrefetching: NO-prfReturns the percentage of read requests that caused a flush.-psReturns the number of blocks of data prefetched for one host readrequest for constant-length prefetching. The prefetch size must beequal to or greater than the segment size. Ranges from 0 to 8192.-privateReturns information on all private LUNs in the storage system.-psmReturns the variable prefetch size. The variable prefetch size isdetermined by multiplying the size of the read request, in blocks,by the multiplier. For example, if the prefetch multiplier is set to 4and the amount of data requested is 2 KB (4 disk blocks), then thevariable prefetch size is 4 times 2 KB or 8 KB (16 disk blocks).-queReturns the queue length, a number.-rbReturns the value for the rebuild priority (ASAP, High, Medium,or Low).-rcReturns the LUN’s read cache state (enabled or disabled).-reads**Returns the number of reads received for each CRU.183
