HP StorageWorks Storage Mirroring for Linux User's Guide (T2558-96078, February 2008)

14 - 19
MirrorChunkSize Block size (in bytes) used in the mirroring process
Values: 1 - 375000
Default: 32768 (32K)
A higher block size value gives you better throughput, but only to a certain point, then it starts
using more memory because of the way memory is allocated and deallocated. A lower block size
value produces slower throughput, but uses memory efficiently. The optimal value is 32768. The
MirrorChunkSize should not be larger than the TCPBufferSize.
MirrorEncryptedFiles Specifies if encrypted files are mirrored
Values:
(
0) Encrypted files are not mirrored
(
1) Encrypted files are mirrored
Default:
1
MirrorOverwrite Determines if the mirror process overwrites existing files
Values:
(0) never overwrite
(
1) always overwrite
(2) overwrite if older
Default: 1
MirrorPrompting This entry is no longer used.
MirrorQueueLimit Maximum number of mirror operations that can be queued on the source machine
Values:
1 - 65535
Default: 1000
MissedPackets Specifies the number of requests sent by the target that go unanswered by the source before
failover occurs
Values:
1 - 65535
Default: 5
MoveOrphanedFiles Specifies if orphaned files are deleted or moved to the directory specified by MoveOrphansDir
Values:
(
1) Rename
(0) Delete
Default: 0
MoveOrphansDir Indicates the name of the directory where orphaned files will be moved if MoveOrphanedFiles=1
Values: any valid path
Default: /var/lib/StorageWorks/StorageMirroring
NameFailover Specifies whether or not to failover machine names
Values:
(
0) Do not failover machine names
(
1) Failover machine names
Default:
1
NetPort Port connection for TCP communications
Values: 1025 - 65535
Default:
1500
If you change this value, the source daemon must be stopped and restarted to implement the
change.
