OpenVMS Alpha System Dump Analyzer Utility Manual

Previous | Contents

Valid client names are listed in the /CLIENT=name qualifier. The /CLIENT, /DEVICE, and /UNIT qualifiers are synonymous and mutually exclusive.

/ELAN

Specifies information from an Emulated LAN (ELAN) that runs over an asynchronous transfer mode (ATM) network. The /ELAN qualifier displays the LAN station Block (LSB) address, device state, and the LSB fields pertinent to an ELAN for both the parent ATM device and the ELAN psuedo-device drivers. It also specifies the name, description, parent device, state, and LAN emulation client (LEC) attributes of the ELAN.

The qualifier /ELAN used with the device qualifier (/LAN/device=ELA) will only display information for the specified device or psuedo-device.

/ERRORS

Specifies that the LSB and UCB error counters be displayed.

/FDDI

Specifies that Fiber Distributed Data Interface (FDDI) information for the LAN be displayed. By default, both CSMA/CD and FDDI information is displayed.

/FULL

Specifies that all information from the LAN, LSB, and UCB data structures be displayed.

/ICOUNTERS

Specifies internal counters of the drivers by displaying the internal counters. If the /ICOUNTERS qualifier is used with the /DEVICE qualifier, the /ICOUNTERS specifies the internal counters of a specific driver.

/QUEUE

Specifies a listing of all queues, whether their status is valid or invalid, and all elements of the queues. If the /QUEUE qualifier is used with the /DEVICE qualifier, the /QUEUE specifies a specific queue.

/SUMMARY

Specifies that only a summary of LAN information (a list of flags, LSBs, UCBs, and base addresses) be printed. This is the default.

/TIMESTAMPS

Specifies the print time information (such as start and stop times and error times) from the device and unit data structures. SDA displays the data in chronological order.

/UNIT=name

Specifies that information be displayed for the specified unit. See the descriptions for /CLIENT=name and /DEVICE=name qualifiers.

/VCI

Specifies the VMS Communication Interface Block (VCIB) for each LAN device with an active VCI user. If the /VCI qualifier is used with the /DEVICE qualifier, the VCIB is only displayed for the specified device.

DESCRIPTION

The SHOW LAN command displays information contained in various local area network (LAN) data structures. By default, or when the /SUMMARY qualifier is specified, SHOW LAN displays a list of flags, LSBs, UCBs, and base addresses. When the /FULL qualifier is specified, SHOW LAN displays all information found in the LAN, LSB, and UCB data structures.

The SHOW LAN/ELAN/DEVICE=HCA command displays information for the ATM device (HCA) driver only.

SHOW LOCK

Displays information about all lock management locks in the system, or about a specified lock.

Format

SHOW LOCK {lock-id|/ADDRESS=n|/ALL (d)|/CACHED |/NAME=name}

PARAMETER

lock-id

Name of a specific lock.

QUALIFIERS

/ADDRESS=n

Displays a specific lock, given the address of the lock block.

/ALL

Lists all locks that exist in the system. This is the default behavior of the SHOW LOCK command.

/CACHED

Displays locks that are no longer valid. The memory for these locks is kept around so that later requests for locks can use them. Cached locks are not displayed in the other SHOW LOCK commands.

/NAME=name

Displays a specified lock with the given name.

DESCRIPTION

The SHOW LOCK command displays the information described in Table SDA-12 for each lock management lock in the system, or for the lock indicated by lock-id. (Use the SHOW SPINLOCKS command to display information about spin locks.) You can obtain a similar display for the locks owned by a specific process by issuing the appropriate SHOW PROCESS/LOCKS command. See the OpenVMS Programming Concepts Manual for additional information.

You can display information about the resource to which a lock is queued by issuing the SHOW RESOURCE command specifying the resource's lock-id.

Table SDA-12 Contents of the SHOW LOCK and SHOW PROCESS/LOCKS Displays
Display Element Description
Process Index¹ Index in the PCB array to a pointer to the process control block (PCB) of the process that owns the lock.
Name¹ Name of the process that owns the lock.
Extended PID¹ Clusterwide identification of the process that owns the lock.
Lock ID Identification of the lock.
PID Systemwide identification of the lock.
Flags Information specified in the request for the lock.
Par. ID Identification of the lock's parent lock.
Granted at Lock mode at which the lock was granted.
Sublocks Identification numbers of the locks that the lock owns.
LKB Address of the lock block (LKB). If a blocking AST has been enabled for this lock, the notation "BLKAST" appears next to the LKB address.
Resource Dump of the resource name. The two leftmost columns of the dump show its contents as hexadecimal values, the least significant byte being represented by the rightmost two digits. The rightmost column represents its contents as ASCII text, the least significant byte being represented by the leftmost character.
Status Status of the lock, information used internally by the lock manager.
Length Length of the resource name.
Mode Processor access mode of the namespace in which the resource block (RSB) associated with the lock resides.
Owner Owner of the resource. Certain resources owned by the operating system list "System" as the owner. Resources owned by a group have the number (in octal) of the owning group in this field.
Copy Indication of whether the lock is mastered on the local system or is a process copy.

¹This display element is produced only by the SHOW PROCESS/LOCKS command.
