Solution Type Technical Instruction Sure Solution 1001924.1 : Determining Memory size, Segment size and Write cache status for Sun StorEdge[TM] A3x00 and Sun StorEdge[TM] A1000.
PreviouslyPublishedAs 202679 Description It is not possible to use the command line interface (CLI) to determine the status of the following for RAID Manager 6.1.1 used on Sun StorEdge[TM] A3x00 and Sun StorEdge[TM] A1000 :- - Cache memory size of RAID controller, - RAID segment size of the LUNs (logical units) - Write-cache status of LUNs This document helps us in determining the above from the module profile taken from the GUI. This can then be used to check status and for remote troubleshooting. Steps to Follow We can find the status of cache memory size, segment size and write-cache status of LUNs by using the raid manager GUI, i.e., by running: /usr/lib/osa/bin/rm6 Once the GUI is running, we can gather a snapshot of the configuration information of the array. This is called the module profile which is an ASCII text file which can be used to determine the cache memory size, segment size and status of the write-cache. How to get module profile ------------------------- 1. Run "/usr/lib/osa/bin/rm6" command as superuser. 2. Select the module from which you wish to gather the module profile. 3. Click on the icon labelled "Maintenance and Tuning" 4. Select a specific RAID module name from which you would like to get the module profile in the "RAID Module" pull down menu. (By default, "All RAID Modules" is selected but at this point, you need to select a specific one rather than "All RAID Modules". (For example, select "sonoma_001".) 5. Click "File" menu -> "Save Module Profile" on the window, then you will see "Save module profile" window. Make sure all items are selected on "Save module profile" window, then click the "OK" button. 6. You will be prompted to enter the filename you want to save the module profile as. Type the absolute pathname for the file to be created, then click on "OK". Once you do this, the module profile for the selected RAID module will be written to the file. Once you have the module profile, you can view the file. The following section will guide you to check the cache memory size of the array, segment size of the individual luns and the write cache status of individual luns. For example, the module profile looks as below:- Example output of module profile: ====================================== Profile for sonoma_001 Profile Generated By: RAID Manager Release 06.22.01.55 Host: sonoma Controllers: Name Serial Number Mode Logical Units A (c1t5d0) 1T00300756 Active 3 B (c2t4d1) 1T92000694 Active 2 Number of Drives = 25 Detailed Controller Information for sonoma_001 Parameters Controller A (c1t5d0) Controller B (c2t4d1) Board Name: Series 3 Series 3 Board ID: 3621 3621 Board Serial Number: 1T00300756 1T92000694 Product ID: StorEDGE A3000 StorEDGE A3000 Product Serial Number: 1T00300756 1T92000694 Vendor ID: Symbios Symbios Date of Manufacture: 02/12/00 05/29/99 Product Revision: 0003 0003 Host Interface: Parallel SCSI Parallel SCSI Host-side ID (dec): 5 4 Boot Level: 03.01.04.00 03.01.04.00 Firmware Level: 03.01.04.75 03.01.04.75 Fibre Channel Level: - - Cache/Processor Size: 64/16 MB 64/16 MB Drives: Detailed Drive Information for sonoma_001 Location Capacity (MB) Status Vendor Product ID [1,0] 17274 Optimal FUJITSU MAA3182S SUN18G [2,0] 17274 Optimal FUJITSU MAA3182S SUN18G [3,0] 17274 Optimal FUJITSU MAA3182S SUN18G [4,0] 17274 Optimal FUJITSU MAA3182S SUN18G [5,0] 17274 Optimal FUJITSU MAA3182S SUN18G [1,1] 17274 Optimal FUJITSU MAA3182S SUN18G [2,1] 17274 Failed FUJITSU MAA3182S SUN18G [3,1] 17274 Optimal FUJITSU MAA3182S SUN18G [4,1] 17274 Optimal FUJITSU MAA3182S SUN18G [5,1] 17274 Optimal FUJITSU MAA3182S SUN18G [1,2] 17274 Optimal FUJITSU MAA3182S SUN18G [2,2] 17274 Optimal FUJITSU MAA3182S SUN18G [3,2] 17274 Optimal FUJITSU MAA3182S SUN18G [4,2] 17274 Optimal FUJITSU MAA3182S SUN18G [5,2] 17274 Optimal FUJITSU MAA3182S SUN18G [1,3] 17274 Optimal FUJITSU MAA3182S SUN18G [2,3] 17274 Failed FUJITSU MAA3182S SUN18G [3,3] 17274 Optimal FUJITSU MAA3182S SUN18G [4,3] 17274 Optimal FUJITSU MAA3182S SUN18G [5,3] 17274 Optimal FUJITSU MAA3182S SUN18G [4,8] 17274 Optimal FUJITSU MAG3182L SUN18G [5,8] 17274 Optimal FUJITSU MAG3182L SUN18G [4,9] 17274 Optimal FUJITSU MAG3182L SUN18G [5,9] 17274 Optimal FUJITSU MAG3182L SUN18G [5,10] 17274 Spare[2,3] FUJITSU MAG3182L SUN18G Detailed Drive Information for sonoma_001 (continued) Location Firmware Version Serial Number Date Code [1,0] 2107 00G08649 9848 [2,0] 2107 00G08364 9848 [3,0] 2107 00G08386 9848 [4,0] 2107 00G04816 9848 [5,0] 2107 00G08258 9848 [1,1] 2107 00G08322 9848 [2,1] 2107 00G01309 9848 [3,1] 2107 00G08630 9848 [4,1] 2107 00G08212 9848 [5,1] 2107 00G08229 9848 [1,2] 2107 00G08234 9848 [2,2] 2107 00G08235 9848 [3,2] 2107 00G08247 9848 [4,2] 2107 00G07833 9848 [5,2] 2107 00G08257 9848 [1,3] 2107 00G08216 9848 [2,3] 2107 00G08195 9848 [3,3] 2107 00G07854 9848 [4,3] 2107 00G06759 9848 [5,3] 2107 00G08332 9848 [4,8] 0707 00523641 9911 [5,8] 0707 00523894 9911 [4,9] 0707 00524078 9911 [5,9] 0707 00523863 9911 [5,10] 0707 00524112 9911 Logical Units (LUNs): Detailed LUN Information for sonoma_001 Capacity LUN Controller (MB) RAID Level 0 c1t5d0 1024 5 1 c2t4d1 1024 5 2 c1t5d2 1024 5 3 c2t4d3 1024 5 4 c1t5d4 1024 1 Detailed LUN Information for sonoma_001 (continued) LUN Associated Drives 0 [1,0] [2,0] [3,0] [4,0] [5,0] 1 [1,1] [2,1] [3,1] 2 [1,2] [2,2] [3,2] 3 [1,3] [2,3] [3,3] 4 [4,1] [5,1] [4,2] [5,2] Detailed LUN Information for sonoma_001 (continued) Segment Write Cache Cache Without LUN Size Cache Mirroring Batteries Status (Blocks) 0 64 Enabled Enabled Disabled Optimal 1 64 * Enabled Enabled Disabled Degraded 2 64 Enabled Enabled Disabled Optimal 3 64 Enabled Enabled Disabled Optimal 4 128 Enabled Enabled Disabled Optimal Drive Group Information for sonoma_001 No. No. Total Remaining of RAID of Capacity Capacity Group LUNS Level Drives (MB) (MB) Unassigned 0 - 6 103644 103407 Hot Spare - - 1 - - 1 1 5 5 68938 67914 2 1 5 3 34469 33445 3 1 5 3 34469 33445 4 1 5 3 34469 33445 5 1 1 4 34469 33445 Logical Unit Information for sonoma_001 Device RAID Cap.

Determining Cache memory size of the controller: In case of A3x00, you can see the cache memory size of both the controllers. In the example below, controller A's cache memory size is 64 MB, and system memory size is 16MB. The same is true for controller B. Note: This should be same on both the controllers. Cache/Processor Size: 64/16 MB 64/16 MB 2. Determining Segment size of LUNs: In case of the following example, LUN 0's segment size is 64 blocks. (1 block is equal to 512 byte.) LUN 4's one is 128 blocks. Detailed LUN Information for sonoma_001 (continued) Segment Write Cache Cache Without LUN Size Cache Mirroring Batteries Status (Blocks) 0 64 Enabled Enabled Disabled Optimal 1 64 Enabled Enabled Disabled Degraded 2 64 Enabled Enabled Disabled Optimal 3 64 Enabled Enabled Disabled Optimal 4 128 Enabled Enabled Disabled Optimal 2.

The asterisk (*) in front of LUN 1 indicates that the write cache for this LUN is disabled. So by this way, we can come to know the memory size of the controller(s), segment size of the LUNs and and the write-cache status of the LUNs from the module profile.

Since we cannot get it using the CLI, the explorer doesn't gather the module profile and we have to ask for it manually.
