Lists filesets that contain data the Cache Manager cannot write back to a File Server machine
Synopsis
cm lsstores [-help]
Options
-help
Prints the online help for this command.
Description
The cm lsstores command lists the fileset ID numbers of filesets that contain data the Cache Manager cannot write back to a File Server machine. This
information comes from the kernel of the workstation on which the command is issued.
On occasion, a File Server machine may be unavailable to the Cache Manager (possibly because the File Server machine is down or because a network problem prevents the Cache Manager from contacting the machine). In such cases, the Cache Manager cannot write data back to the File Server machine. The Cache Manager displays a message on the screen to notify the user that it cannot write the data to the unavailable machine. If possible, it also returns a failure code to the application program using the data.
The Cache Manager keeps the unstored data in the cache and continues to attempt to contact the File Server machine until it can store the data. (The frequency with which it attempts to reach a File Server machine is defined with the -pollinterval option of the fxd command issued on that File Server machine.) In the meantime, corrective measures can be taken to alleviate the problem that prevents the data from being stored; for example, the File Server machine can be restarted. Once the problem is alleviated, the Cache Manager can reach the File Server machine and store the data.
The Cache Manager discards unstored data only when
· It needs to make room in the cache for other data. Given an average-sized cache with average usage, the Cache Manager rarely needs to discard unstored data.
· The cm resetstores command is issued to force it to discard unstored data from the cache.
Because unstored data discarded from the cache cannot be recovered, any problem that prevents data from being written to a File Server machine should be handled promptly.
Privilege Required
No privileges are required.
Output
If the Cache Manager cannot store data to one or more filesets, the command displays the fileset ID number of each fileset to which data cannot be stored. If the Cache
Manager has been able to store all data, the command displays the following message:
No failed stores are being retried.
