(3) Parameters used when displaying path information

When displaying path information, if the -item parameter or the -c parameter is specified at the same time as the -path parameter, you can select the items to display and display a summary of path information. This section describes each parameter, path information and displayed items.

Parameters (to display path information)

-path
When you specify the -path parameter and do not specify either the -c or -item parameter, the command displays information about the paths without abbreviating or selecting items.
In the subsequent sub-parameters (following -path), you can filter the paths to be listed (-hdev) and sort the list (-srt). When you omit both parameters, the command displays information for all the paths in order of ascending AutoPATH_IDs.
For details on what is displayed in each item, see Table 7-11 Displayed path information.
AutoPATH_IDs displayed by the -path parameter depend on the sequence in which HDLM detects the paths when a host is started. Because of this, make sure that you use the path name (PathName) to identify a path.
The subsequent sub-parameters (following -path) are:

-hdev host-device-name
Filters the information only for the paths accessing the specified host device.
Specify a drive letter to indicate the desired host device. You cannot specify the host device unless a drive letter has been assigned. The host-device-name string is case-sensitive. If the command finished by displaying the KAPL01064-W or KAPL01013-E message, follow the action recommended in the message.

-stname
Use this parameter for the Thunder 9200/9500V Series, Lightning 9900/9900V Series, TagmaStore, or Universal Storage Platform V to display the model ID of the storage subsystem in the product ID element of the DskName field. When this parameter is omitted, the command displays the product ID or emulation type of the storage subsystem instead.
For more information pertaining to the storage subsystem and corresponding product ID, see Table 7-13 Product ID displayed by the view -path operation.

-iem
Use this parameter to add IEP to path information and display information about intermittent errors.

-srt {pn|lu|cp}
Use this parameter to sort the list of path information in ascending order, according to the specified sorting keys.
The sorting keys are as follows: the first sorting key is the name of the storage subsystem (DskName), the second sorting key is the value specified by the -srt parameter, and the third sorting key is AutoPATH_ID.
The parameter values available to specify the second sorting key are:
  • pn: Path name
  • lu: LU number of the storage subsystem
  • cp: Port number of the channel adapter
When the -srt parameter is omitted, the path information is listed in order of ascending AutoPATH_IDs.

-exlu
  • When an HDLM management-target device contains the EMC DMX series, EMC CX series, or HP EVA series
    If this parameter is specified, the entire 32 digits of the iLU are displayed without truncating it to 13 digits. If this parameter is not specified, the iLU of the EMC DMX series, EMC CX series, and HP EVA series is displayed as 16 digits with the 14th to 16th digits displayed as periods (...).
  • When an HDLM management-target device is configured of only the Thunder 9200/9500V Series, Lightning 9900/9900V Series, TagmaStore, or Universal Storage Platform V
    16 digits are displayed for the iLU even if this parameter is specified.

-t
Does not display the title for each information item.

Example
When the -exlu parameter is not specified:
[Figure]
When the -exlu parameter is specified:
[Figure]

Parameters (to display path information, by selecting a display item)

-path -item
When you specify the -path parameter together with the -item parameter, the command only displays the items specified by the value of the -item parameter.
If you specify no value for the -item parameter, only the PathID and the Status fields are displayed.
Table 7-10 Items that can be selected by the -path -item parameter and parameter values that can be specified after the -path -item parameter shows the items that can be selected by using the -item parameter and the parameter values that can be specified after the -item parameter.

Table 7-10 Items that can be selected by the -path -item parameter and parameter values that can be specified after the -path -item parameter

Selectable items Parameter values that can be specified after the -path -item parameter
PathID# None
Status# None
PathName pn
DskName dn
iLU lu
ChaPort cp
Type type
IO-Count ic
IO-Errors ie
DNum dnu
HDevName hd
IEP iep

#
Because both PathID and Status are always displayed, they do not require any parameters to be specified.

In the subsequent sub-parameters (following -path -item), you can filter the paths to be listed (-hdev) and sort the list (-srt). When you omit both parameters, the command displays information for all the paths in order of increasing AutoPATH_IDs.
The subsequent sub-parameters (following -path -item) are:

-hdev host-device-name
Filters the information only for the paths accessing the specified host device.
Specify a drive letter to indicate the desired host device. You cannot specify the host device unless a drive letter has been assigned.
The host-device-name string is case-sensitive.
When you specify this parameter, HDevName is displayed by default. Therefore, it is not necessary to specify hd for the -item parameter.

-stname
Use this parameter for the Thunder 9200/9500V Series, Lightning 9900/9900V Series, TagmaStore, or Universal Storage Platform V to display the model ID of the storage subsystem in the product ID element of the DskName field. When this parameter is omitted, the command displays the product ID or emulation type of the storage subsystem instead.
For more information pertaining to the storage subsystem and corresponding product ID, see Table 7-13 Product ID displayed by the view -path operation.
When you use this parameter, DskName is displayed by default. Therefore, it is not necessary to specify dn for the -item parameter.

-srt {pn|lu|cp}
Use this parameter to sort the list of path information in ascending order, according to the specified sorting keys.
The sorting keys are as follows: the first sorting key is the name of the storage subsystem (DskName), the second sorting key is the value specified by the -srt parameter, and the third sorting key is AutoPATH_ID.
The parameter values available to specify the second sorting key are:
  • pn: Path name
  • lu: LU number of the storage subsystem
  • cp: Port number of the channel adapter
When the -srt parameter is omitted, the path information is listed in order of ascending AutoPATH_IDs.
When you use this parameter, the items used for the sorting keys (DskName, AutoPATH_ID, and the item specified by this parameter) are displayed by default. Therefore, it is not necessary to specify these items for the -item parameter.

-exlu
  • When an HDLM management-target device contains the EMC DMX series, EMC CX series, or HP EVA series
    If this parameter is specified, the entire 32 digits of the iLU are displayed without truncating it to 13 digits. If this parameter is not specified, the iLU of the EMC DMX series, EMC CX series, and HP EVA series is displayed as 16 digits with the 14th to 16th digits displayed as periods (...).
  • When an HDLM management-target device is configured of only the Thunder 9200/9500V Series, Lightning 9900/9900V Series,TagmaStore, or,Universal Storage Platform V
    16 digits are displayed for the iLU even if this parameter is specified.

-t
Does not display the title for each information item.

Example
In the following example, IO-Count is selected as the display item and the path information is sorted in ascending order of the LUs.
[Figure]

Parameters (to display a summary of path information)

-path -c
If the -c parameter is specified at the same time as the -path parameter, only PathID, DskName, iLU, CP, Status, and Type are displayed from the path information managed by HDLM. The displayed contents are shortened so that each instance of path information is displayed on a single line.
The items that are displayed are PathID, DskName, iLU, CP, Status, and Type.
For details on what is displayed in each item, see Table 7-11 Displayed path information.
When you use the -c parameter, the number of characters that can be displayed in the product ID element of the DskName field is limited to 10. Therefore, when there are 11 or more characters in the product ID, the 8th and following characters are abbreviated to ellipses (...).
The subsequent sub-parameters (following -path -c) are:

-stname
Use this parameter for the Thunder 9200/9500V Series, Lightning 9900/9900V Series, TagmaStore, or Universal Storage Platform V to display the model ID of the storage subsystem in the product ID element of the DskName field. When this parameter is omitted, the command displays the product ID or emulation type of the storage subsystem instead.
For more information pertaining to the storage subsystem and corresponding product ID, see Table 7-13 Product ID displayed by the view -path operation.

-srt {lu|cp}
Use this parameter to sort the list of path information in ascending order, according to the specified sorting keys.
The sorting keys are as follows: the first sorting key is the name of the storage subsystem (DskName), the second sorting key is the value specified by the -srt parameter, and the third sorting key is AutoPATH_ID.
The parameter values available to specify the second sorting key are:
  • lu: LU number of the storage subsystem

Parameters (to display LU information (by adding items to be displayed))

-lu -item
The items specified with the -item option are added to the items to be displayed by the -lu option and displayed.
If no value or all is specified for the -item parameter, all the items that can be added are displayed.
Table 7-14 Items that can be added by using the -lu -item parameter and parameters that can be specified after the -lu -item parameter shows the items that can be added by using the -item parameter and the parameters that can be specified after the -item parameter.

Table 7-14 Items that can be added by using the -lu -item parameter and parameters that can be specified after the -lu -item parameter

SLPR slpr
PathName pn
ChaPort cp
CLPR clpr
Type type
IO-Count ic
IO-Errors ie
DNum dnu
IEP iep
All items are displayed all
In the subsequent sub-parameters (-hdev or -pathid), you can filter the LU information to be displayed. When you omit both parameters, the command displays the information about all the LUs recognized by HDLM.
For details on the contents of each displayed item, see Table 7-16 Displayed LU information.
The subsequent sub-parameters are:

-hdev host-device-name
Filters the information only for the paths accessing the specified host device.
Specify a drive letter to indicate the desired host device. You cannot specify the host device unless a drive letter has been assigned.
The host-device-name string is case-sensitive. If the command finished by displaying the KAPL01064-W or KAPL01013-E message, follow the action recommended in the message.

-pathid AutoPATH_ID
Use this parameter to display only the information about the LU to which the path with the specified AutoPATH_ID is connected.

-exlu
  • When an HDLM management-target device is the EMC DMX series, EMC CX series, or HP EVA series
    If this parameter is specified when a device managed by HDLM is the EMC DMX series, EMC CX series, and HP EVA series, the entire 32 digits of the iLU are displayed without truncating it to 13 digits. If this parameter is not specified, the iLU of the EMC DMX series, EMC CX series, and HP EVA series is displayed as 16 digits with the 14th to 16th digits displayed as periods (...).
  • When an HDLM management-target device is the Thunder 9200/9500V Series, Lightning 9900/9900V Series, TagmaStore, or Universal Storage Platform V
    Less than 16 digits are always displayed for the iLU whether or not this parameter is specified.

-t
Does not display the title for each information item.

Example
The following example shows how to add SLPR, PathName, ChaPort, CLPR, Type IO-Count, IO-Errors, DNum, and IEP to the displayed items for LU information.

Parameters (to display a summary of LU information)

-lu -c
When the -c parameter is specified with the -lu parameter, a summary of LU configuration information is displayed on a line. The total number of paths recognized by HDLM and the number of online paths are displayed for each LU.
Note that:
  • In the Thunder 9200/9500V Series, Lightning 9900/9900V Series, TagmaStore, and Universal Storage Platform V, LU information is displayed for each storage subsystem.
  • In the EMC DMX series and EMC DMX, LU information is displayed for each vendor ID.
  • In the HP EVA series, LU information is displayed for each vendor_ID_product_ID.
You cannot specify the -c parameter together with the -hdev or -pathid parameter.
For details on the contents of each display item, see Table 7-16 Displayed LU information.

-exlu
  • When an HDLM management-target device contains the EMC DMX series, EMC CX series, or HP EVA series
    If this parameter is specified, the entire 32 digits of the iLU are displayed without truncating it to 13 digits. If this parameter is not specified, the iLU of the EMC DMX series, EMC CX series, and HP EVA series is displayed as 16 digits with the 14th to 16th digits displayed as periods (...).
  • When an HDLM management-target device is configured of only the Thunder 9200/9500V Series, Lightning 9900/9900V Series, TagmaStore, or Universal Storage Platform V
    16 digits are displayed for the iLU even if this parameter is specified.

-t
Does not display the title for each information item.
