Post subject: | 3par 7400 does not initialise chunklets |
Hey everybody I have a strange problem with 3par 7400 2-node system I had to replace a node on it and wanted to start from scratch so I performed deinstallation So now it is not able to perform OOTB fully, specifically it does not create admin volume It sees both nodes, the cage and cabling tests are passing, it sees my 4 disks admitpd admits them and it says all 4 are valid but next it is supposed to start chunklets initialization and this does not happen it can wait forever saying that 20 chunklets for admin volume are not clean yet showpd -c then says all chunklets are uninitialized OOTB stress test log also shows that no chunklets are initialized during initialization stage Code: root@9277883-1 Mon Oct 10 16:29:46:/# showtask -d 11792 Id Type Name Status Phase Step -------StartTime------- -FinishTime- -Priority- ---User---- 11792 system_task OOTB_stress active 1/1 0/1 2022-10-10 14:51:00 MSK - n/a sys:3parsys Detailed status: 2022-10-10 14:51:00 MSK Created task. 2022-10-10 14:51:00 MSK Updated Executing "OOTB_stress" as 0:14060 2022-10-10 14:51:01 MSK Updated Admitting new PDs...Checking for drive table upgrade packages. 2022-10-10 14:51:01 MSK Updated Package check completed 2022-10-10 14:51:02 MSK Updated 0 disks admitted 2022-10-10 14:51:02 MSK Updated 2022-10-10 14:51:03 MSK Updated Waiting for chunklet init to complete 2022-10-10 14:56:04 MSK Updated 7148 chunklets to clean or 54:59 to go 2022-10-10 15:01:06 MSK Updated 7148 chunklets to clean or 49:58 to go 2022-10-10 15:06:07 MSK Updated 7148 chunklets to clean or 44:57 to go 2022-10-10 15:11:08 MSK Updated 7148 chunklets to clean or 39:55 to go 2022-10-10 15:16:10 MSK Updated 7148 chunklets to clean or 34:54 to go 2022-10-10 15:21:11 MSK Updated 7148 chunklets to clean or 29:53 to go 2022-10-10 15:26:12 MSK Updated 7148 chunklets to clean or 24:51 to go 2022-10-10 15:31:13 MSK Updated 7148 chunklets to clean or 19:50 to go 2022-10-10 15:36:15 MSK Updated 7148 chunklets to clean or 14:49 to go 2022-10-10 15:41:16 MSK Updated 7148 chunklets to clean or 9:48 to go 2022-10-10 15:46:17 MSK Updated 7148 chunklets to clean or 4:46 to go 2022-10-10 15:51:19 MSK Updated 7148 chunklets to clean or 0:-15 to go 2022-10-10 15:51:19 MSK Updated Waiting for battery tests to complete 2022-10-10 15:52:25 MSK Updated Starting stress on node 0 2022-10-10 15:52:26 MSK Updated Starting stress on node 1 2022-10-10 15:52:27 MSK Updated Stress started, waiting for stress completion. root@9277883-1 Mon Oct 10 16:29:48:/# showpd -c ------- Normal Chunklets -------- ---- Spare Chunklets ---- - Used - -------- Unused -------- - Used - ---- Unused ---- Id CagePos Type State Total OK Fail Free Uninit Unavail Fail OK Fail Free Uninit Fail 0 0:0:0 SSD normal 1787 0 0 0 1787 0 0 0 0 0 0 0 1 0:1:0 SSD normal 1787 0 0 0 1787 0 0 0 0 0 0 0 2 0:2:0 SSD normal 1787 0 0 0 1787 0 0 0 0 0 0 0 3 0:3:0 SSD normal 1787 0 0 0 1787 0 0 0 0 0 0 0 ---------------------------------------------------------------------------------------- 4 total 7148 0 0 0 7148 0 0 0 0 0 0 0 root@9277883-1 Mon Oct 10 16:30:38:/# Code: root@9277883-0 Mon Oct 10 18:53:13:~# showversion Release version 3.3.1 (MU3) Patches: P58 Component Name Version CLI Server 3.3.1 (P58) CLI Client 3.3.1 System Manager 3.3.1 (P58) Kernel 3.3.1 (MU3) TPD Kernel Code 3.3.1 (MU3) TPD Kernel Patch 3.3.1 (P58) I see no events regarding this just see that cage is constantly changing its state showpdch -cng says all chunklets have to be cleaned but nothing happens, the system cleans nothing Does anybody know where to dig next or how to trigger chunklets initialization manually? |

Pretty sure you need at least 6 disks in a 3PAR. 4 is probably not enough. |

Thanks for the advice but adding disks does not help, just added another 4 and it still does nothing, does not initialize anything Okay, so now you have 8x SSDs, that should be enough. Did you do back in the box, out of the box again? What type of SSDs do you have? (showpd -i)? Side note…. Your system has a very strange serial number. In legacy 3PAR each generation had it’s own range of serials… V-class/10000 started with 14 and 7000 started with 16. Yours start with 92….. |

Yes, I restarted the OOTB after adding disks and it still did not initialize chunklets Finally I managed to resolve the issue by rebooting to 3.2.2 which I had on altroot after admithw in 3.2.2 it worked and started initialization process Then I rebooted to 3.3.1 (MU3) once again and it continued to initialize chunklets properly Then I was able to update to 3.3.1 (MU5) and with this version it wipes and runs OOTB normally I guess my 3.3.1 (MU3) was somehow upgraded incorrectly or has a bug Patched MU5 seems working just fine As for SN - yes, it has that number printed on a label on the cage |
